1. Influence of light on ad- and desorption processes on titanium dioxide surfaces towards efficient CO2 photoreduction, P. Naliwajko, N.G. Moustakas, M. Klahn, T. Peppel, J. Strunk, Physical Chemistry Chemical Physics (PCCP), 27 (2025), 6845-6849. DOI: 10.1039/D4CP04279D

Abstract: This work addresses the often-overlooked effect of light-induced sorption behavior of CO2 on powder TiO2 surfaces, as potential first step to photocatalytic CO2 activation. These investigations will lead to a more detailed understanding of the light-induced chemistry of CO2 on TiO2, to eventually unravel the CO2 photoreduction mechanism.

2. Design of SrTiO3-based catalysts for photocatalytic CO2 reduction, B. Boga, N.G. Moustakas, Y. Han, H. Jiao, P. Naliwajko, S. Ding, A. B. Ngo, A. Hezam, T. Peppel, V.-M. Christea, N. Steinfeldt, J. Strunk, 2024, Catalysis Science and Technology (Catal. Sci. Technol.), 14 (2024), 3459-3472. DOI: 10.1039/D4CY00313F

Abstract: Herein, the preparation of SrTiO3-based catalysts (i.e., NiO/support, Au-support and Au–NiO/support, where the supports were SrTiO3 and SrTiO3–SrCO3) for photocatalytic CO2 reduction considering strategic design principles is presented. The samples were comprehensively analyzed via complementary methods, such as SEM-EDX, XRD, nitrogen sorption, XPS and UV-vis (DRS), in situ EPR and in situ DRIFTS. The CO2 photoreduction activity of the samples was assessed in a high-purity gas-phase photoreactor under batch conditions. The investigations highlighted that the reaction pathway (i.e., selective H2 and C2H6 production vs. CH4) can be influenced by the modification of the electronic properties (i.e., Fermi level alignment), the interaction between Au NPs and oxygen vacancies (i.e., in situ EPR) and the enhanced charge separation in the presence of SrCO3. The participation of the structural carbonates in the reaction in association with the functionality of the components is discussed.

3. Performance of Sm-doped TiO2 in photocatalytic antibiotic degradation and photocatalytic CO2 reduction, A. Kutuzova, J-O Moritz, N.G. Moustakas, T. Dontsova, T. Peppel, J. Strunk. Applied Nanoscience, 2023, 1-16. DOI: 10.1007/s13204-023-02832-3

Abstract: Sm-doped TiO2 powders with different Sm loadings (0.7–2 wt.%) were successfully synthesized via a simple hydrothermal method using commercial P25 TiO2 and self-synthesized TiO2 as initial TiO2 nanoparticles. Their physicochemical properties were investigated by means of powder X-ray analysis (PXRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), diffuse reflectance spectroscopy (DRS), and nitrogen physisorption. Their photocatalytic activity was first assessed in the degradation and mineralization of aqueous solutions of antibiotics ciprofloxacin (CIP) and sulfamethoxazole (SMX) under simulated solar irradiation with the 1wt.% Sm-loaded catalysts being the most active. More than 90% of CIP was degraded within 30 min and more than 85% was mineralized within 6 h of the photocatalytic process by the best performing samples (> 60% and > 80% of SMX, respectively). Residual antibiotic activity tests confirmed that CIP solutions treated with Sm-doped TiO2 catalysts did not exhibit toxicity toward E.coli. The photocatalytic activity of Sm-TiO2 catalysts were also investigated in photocatalytic CO2 reduction in batch under 6 h irradiation of a 200 W Hg/Xe lamp. The maximum production of CH4 over the Sm-doped commercial P25 TiO2 and self-synthesized TiO2 was 81 ppm h-1 g-1 and 129 ppm h-1 g-1, respectively. The better photocatalytic performance of the latter could be ascribed to the well-developed specific surface area and better adsorption properties of the material.

4. A high-purity gas-phase photoreactor for reliable and reproducible photocatalytic CO2 reduction measurements, N.G. Moustakas, M. Klahn, M. Dilla, A. Pougin, T. Peppel, B.T. Mei, S. Ristig, J. Strunk. Hardware X, 15 (2023). DOI: 10.1016/j.ohx.2023.e00448

5. Role of SrCO3 on photocatalytic performance of SrTiO3-SrCO3 composites, B. Boga, N. Steinfeldt, N.G. Moustakas, T. Peppel, H. Lund, J. Rabeah, Z. Pap, V.-M. Cristea, J. Strunk, Catalysts, 12 (2022), Pages 978-. DOI: 10.3390/catal12090978

Abstract: Perovskites such as SrTiO3 are interesting for photocatalytic applications due to their structure-related and electronic properties. These properties are influenced by the presence of SrCO3 which is often formed simultaneously during the hydrothermal synthesis of SrTiO3. In this study, SrTiO3-SrCO3 composites with different contents of SrCO3 (5–24 wt%) were synthesized. Their morphological, structural, and optical properties were investigated using complementary methods such as scanning electron microscopy (SEM), X-ray diffraction (XRD), nitrogen sorption, and diffuse reflectance spectroscopy (DRS). Their photocatalytic activity was assessed during the degradation of diclofenac (DCFNa) in aqueous solution and CO2 photoreduction under Xe lamp irradiation. Improved photocatalytic efficiency in DCFNa degradation was observed for all the studied composites in comparison with SrTiO3, and the highest mineralization efficiency was obtained for the sample with 21 wt% SrCO3 content. The presence of SrCO3 led to an increased concentration of active species, such as •OH radicals. Otherwise, its presence inhibits CH4 and C2H6 production during CO2 photoreduction compared with pure SrTiO3.

6. Comparative studies of oxygen-free semiconductors in photocatalytic CO2 reduction and alcohol degradation, F. Lorenz, N.G. Moustakas, T. Peppel, J. Strunk, Chemie Ingenieur Technik, 94, 2022, 11. DOI: 10.1002/cite.202200107

Abstract: Commercially available α-SiC, β-SiC, GaN, ZnTe and self-synthesized g-C3N4 were investigated in a comparative study regarding their photocatalytic capabilities in CO2 reduction and alcohol degradation. Under reproducible high-purity solid-gas conditions none of the tested materials promoted CO2 reduction using H2O as proton donor, although TiO2 P25 has been shown to produce significant amounts of CH4 under similar conditions. Replacing H2O with 2-propanol led to hydrocarbon formation which could solely be attributed to alcohol degradation while no CO2 reduction took place.

7. Pivotal role in holes in photocatalytic CO2 reduction on TiO2, Chemistry – A European Journal, N.G. Moustakas, F. Lorenz, M. Dilla, T. Peppel, J. Strunk, Chemistry: A European Journal, 27 (2021), Pages 17213-17219. DOI: 10.1002/chem.202103070

Abstract: Evidence is provided that in a gas-solid photocatalytic reaction the removal of photogenerated holes from a titania (TiO2) photocatalyst is always detrimental for photocatalytic CO22 reduction. The coupling of the reaction to a sacrificial oxidation reaction hinders or entirely prohibits the formation of CH4 as a reduction product. This agrees with earlier work in which the detrimental effect of oxygen-evolving cocatalysts was demonstrated. Photocatalytic alcohol oxidation or even overall water splitting proceeds in these reaction systems, but carbon-containing products from CO2 reduction are no longer observed. H2 addition is also detrimental, either because it scavenges holes or because it is not an efficient proton donor on TiO2. The results are discussed in light of previously suggested reaction mechanisms for photocatalytic CO2 reduction. The formation of CH4 from CO2 is likely not a linear sequence of reduction steps but includes oxidative elementary steps. Furthermore, new hypotheses on the origin of the required protons are suggested.

8. Transferring photocatalytic CO2 reduction mediated by Cu(N^N)(P^P)+ complexes from organic solvents into ionic liquid media, P. A. F. Cortés, M. Marx, N.G. Moustakas, F. Brunner, C. Housecroft, E. Constable, H. Junge, M. Beller, J. Strunk, Green Chemistry, 2020, 22, 4541-4549. DOI: 10.1039/D0GC01627F

Abstract: Photocatalytic carbon dioxide reduction utilizing metal complexes based on the earth-abundant transition metals iron and copper was transferred from organic solvents into ionic liquids with high selectivity and moderate turn-over numbers. Different classes of ionic liquids were evaluated to determinate the CO/H2 selectivity of the process. High-purity conditions were utilized to validate that CO was a result of COsub>2</sub> reduction and not resulting from other carbon sources. In addition, a novel copper-based photosensitizer was synthesized and its photo- and electrochemical properties were investigated.

9. Enhanced photocatalytic performance of polymeric carbon nitride through combination of iron loading and hydrogen peroxide treatment, V.V. Thang, S. Bartling, T. Peppel, H. Lund, C. Kreyenschulte, J. Rabeah, N.G. Moustakas, A.-E. Surkus, T.H. Duc, N. Steinfeldt, Colloids and Surfaces A, 589 (2020), Pages 124383. DOI: 10.1016/j.colsurfa.2019.1243839

Abstract: Polymeric carbon nitride (p-C3N4) based materials have shown great potential as photocatalysts for degradation of pollutants from wastewater. In this work p-C3N4 was synthesized from urea or ferric chloride/urea by pyrolysis followed by a post-treatment with hydrogen peroxide (H2O2). The prepared materials were characterized by physico-chemical methods in order to study their structural and electronic features. The characterization results revealed that iron was present in p-C3N4 as a Fe3O4 phase. The H2O2 treatment did not only modify the p-C3N4 framework through the generation of oxygen functional groups and defect sites but it also affected the size, distribution, and oxidation state of iron oxide. The photocatalytic activity of the catalysts was tested through the degradation of methyl orange under visible and white light irradiation. In comparison, the iron oxide containing p-C3N4 post-treated with H2O2 sample shows superior photocatalytic performance towards methyl orange degradation. This might be attributed to the valence and conduction band levels of the composite material, an inhibited recombination of photogenerated charge carriers as well as a synergistic effect of iron species and the oxygen containing functional groups or defects present in p-C3N4.

10. Judging the feasibility of TiO2 as photocatalyst for chemical energy conversion by quantitative reactivity determinants, M. Dilla, N.G. Moustakas, A.E. Becerikli, T. Peppel, A. Springer, R. Schlögl, J. Strunk, S. Ristig, Physical Chemistry Chemical Physics, 21 (2019), Pages 13144-13150. DOI: 10.1039/C9CP00981G

Abstract: In this study we assess the general applicability of the widely used P25-TiO2 in gas-phase photocatalytic CO2 reduction based on experimentally determined reactivity descriptors from classical heterogeneous catalysis (productivity) and photochemistry (apparent quantum yield/AQY). A comparison of the results with reports on the use of P25 for thermodynamically more feasible reactions and our own previous studies on P25-TiO2 as photocatalyst imply that the catalytic functionality of this material, rather than its properties as photoabsorber, limits its applicability in the heterogeneous photocatalytic CO2 reduction in the gas phase. The AQY of IrO2/TiO2 in overall water splitting in a similar high-purity gas-solid process was four times as high, but still far from commercial viability.

11. Characterization and effect of Ag(0) vs. Ag(I) species and their localized plasmon resonance on photochemically inactive TiO2, C.T. Handoko, N.G. Moustakas, T. Peppel, A. Springer, F.E. Oropeza, A. Huda, M. D. Bustan, B. Yudono, F. Gulo, J. Strunk, Catalysts, 9 (2019), Pages 323. DOI: 10.3390/catal9040323

Abstract: Commercial TiO2 (anatase) was successfully modified with Ag nanoparticles at different nominal loadings (1%–4%) using a liquid impregnation method. The prepared materials retained the anatase structure and contained a mixture of Ag0 and AgI species. Samples exhibited extended light absorption to the visible region. The effect of Ag loading on TiO2 is studied for the photocatalytic reduction of CO2 to CH4 in a gas–solid process under high-purity conditions. It is remarkable that the reference TiO2 used in this work is entirely inactive in this reaction, but it allows for studying the effect of Ag on the photocatalytic process in more detail. Only in the case of 2% Ag/TiO2 was the formation of CH4 from CO2 observed. Using different light sources, an influence of the localized surface plasmon resonance (LSPR) effect of Ag is verified. A sample in which all Ag has been reduced to the metallic state was less active than the respective sample containing both Ag0 and Ag+, indicating that a mixed oxidation state is beneficial for photocatalytic performance. These results contribute to a better understanding of the effect of metal modification of TiO2 in photocatalytic CO2 reduction.

12. Photocatalytic CO2 reduction on TiO2-based materials under controlled reaction conditions: Systematic insights from a literature study, N.G. Moustakas, J. Strunk, Chemistry: A European Journal, 24 (2018), Pages 12739-12746. DOI: 10.1002/chem.201706178

13. Photocatalytic degradation of salicylic acid and caffeine emerging contaminants using titania nanotubes, M. Arfanis, P. Adamou, N.G. Moustakas, T. Triantis, A.G. Kontos and P. Falaras, Chemical Engineering Journal, 310 (2017), Pages 525-536. DOI: 10.1016/j.cej.2016.06.098

Abstract: Heterogeneous photocatalysis can be a suitable add-on process to conventional wastewater treatment methods aiming to the full degradation of emerging contaminants contributing to water pollution. This work examines the photo-degradation of two frequently detected emerging contaminants (caffeine and salicylic acid) using titanium dioxide nanotubular films (TNTs) so as commercial TiO2 nanoparticulate films (Evonik P25) for comparison. The TNT films were prepared by electrochemical anodization of titanium metal and reached lengths of 20 μm, with a high growth rate (10 μm/h). They present an open porous structure with large specific surface area suitable for efficient adsorption of the contaminants and formation of a large number of photocatalytic active sites. After calcination at 450 °C, TNT films obtain the anatase crystal structure, absorb well in the UV range and present significant photocatalytic activity with high degradation rates for both examined emerging pollutants. Furthermore, they present small variability of their photocatalytic efficiency in a big range of the solutions pH values and under consecutive photocatalytic cycles, rendering them suitable at various wastewater treatment conditions.

Silva, J.M. Dona-Rοdriguez, G.Em. Romanos, P. Falaras, Applied Catalysis B: Environmental, 178 (2015), Pages 12–19. DOI: 10.1016/j.apcatb.2014.11.021

15. CO2 Captured in Zeolitic Imidazolate Frameworks: Raman Spectroscopic Analysis of Uptake and Host–Guest Interactions, A. G. Kontos, V. Likodimos, C. M. Veziri, E. Kouvelos, N.G. Moustakas, G.N. Karanikolos, G.Em. Romanos, P. Falaras, ChemSusChem 2014, 7, 1696 – 1702. DOI: 10.1002/cssc.201301323

Abstract: Zeolitic imidazolate frameworks (ZIFs) exhibit enhanced selectivity and increased CO2 uptake due to the incorporation of functional imidazolate units in their structure as well as their extensive porosity and ring flexibility. In situ Raman investigation of a representative host compound, ZIF-69, in practical CO2 pressure and temperature regimes (0–10 bar and 0–64 °C) correlates well with corresponding macroscopic CO2 sorption data and shows clear clear spectroscopic evidence of CO2 uptake. Significant positive shift of the 159 cm2 phenyl bending mode of the benzimidazole moiety indicates weak hydrogen bonding with CO2 in the larger cavities of the ZIF matrix. Raman spectroscopy is shown to be an easy and sensitive tool for quantifying CO2 uptake, identifying weak host–guest interactions and elucidating CO2 sorption mechanism in ZIFs.

16. Visible light active TiO2 photocatalytic filtration membranes with improved permeability and low energy consumption, N.G. Moustakas, F.K. Katsaros, A.G. Kontos, G.Em. Romanos, D.D. Dionysiou, P. Falaras, Catalysis Today, 224 (2014), 56-69. DOI: 10.1016/j.cattod.2013.10.063

Abstract: Visible light active ultrafiltration (UF) membranes coated with modified nanostructured titania (m-TiO2) were for the first time developed using a sol–gel preparation technique combined with a dip-coating deposition procedure. It has been confirmed that the structural, morphological and physicochemical properties of the modified titania membranes strongly depend on the dip-coating and calcination rates. The modified membranes were incorporated in a water purification photocatalytic reactor in continuous flow filtration conditions and tested for the photocatalytic degradation of azo-dye model compounds (namely methyl orange – MO and methylene blue – MB) with very promising results. The photocatalytic experiments took place under ambient operating temperature and low pressure without any compromise on the efficiency of the membrane’s permeate flux. Without irradiation, the permeability drops with increasing flow rates of the solution that is forced to penetrate through their pore structure. The photocatalytic efficiency depends on the effluent flow rate however, under both UV and visible light, the permeability was continuously increasing due to the photoinduced hydrophilicity effect. Compared to MO, the MB pollutant was degraded at much higher rate due to its better adsorption, independently of the type of the membrane. The permeability of the membranes increases with the volume treated due to the wettability of the m-TiO2 treated membrane, rendering the need for regeneration or anti-fouling procedures unnecessary and making the process more energy efficient. Due to the low temperature function and the photoinduced hydrophilic effect of the modified TiO2 photocatalytic UF membranes, the photocatalytic reactor can efficiently work without any extra device, fact that leads to low installation and operating costs and provides an energy efficient procedure of cleaning polluted aqueous solutions.

17. TiO2, surface modified TiO2 and graphene oxide-TiO2 photocatalysts for degradation of water pollutants under near-UV/Vis and visible light, Luisa M. Pastrana-Martínez, Sergio Morales-Torres, Athanassios G. Kontos, Nikolaos G. Moustakas, Joaquim L. Faria, José M. Doña-Rodríguez, Polycarpos Falaras, Adrián M.T. Silva, Chemical Engineering Journal, 224 (2013), 17–23. Publication used as cover of the journal. DOI: 10.1016/j.cej.2012.11.040

Abstract: In this work the photocatalytic activity between a TiO2 catalyst synthesized by a modified sol–gel method (ECT), TiO2 nanoparticles surface modified with organic shell layer (m-TiO2) and a graphene oxide-TiO2 composite (GOT-3.3) was compared. Diphenhydramine (DP) pharmaceutical and methyl orange (MO) azo-dye were used as model water pollutants under both near-UV/Vis and visible light irradiation. The TiO2 photocatalyst from Evonik Degussa Corporation (P25) was used as reference material and the pseudo-first order rate constants (k) and total organic carbon (TOC) removal were determined. Under near-UV/Vis irradiation, the results show that ECT and GOT-3.3 are highly active photocatalysts for the degradation of DP (k = 64.5 × 10-3 and 62 × 10-3 min-1, respectively) and mineralization (TOC removal of 55% and 50%, respectively) being the overall performance comparable to that obtained with P25 (k = 56 × 10-3 min-1 and 48% of TOC removal). The composite GOT-3.3 presents a markedly higher activity for conversion of the MO dye (k = 126 × 10-3, 52 × 10-3, 49 × 10-3, 18.1 × 10-33 min-1 for GOT-3.3, P25, ECT and m-TiO2, respectively) as well as for its mineralization, with TOC removals tailoring the same order. Under visible light illumination, P25 is practically inactive and GOT-3.3 (for DP) and m-TiO2 (for MO) are the photocatalysts with better properties than P25, or even than ECT. Scavenger agents were used as a diagnostic tool for the analysis of the photocatalytic mechanism, being defined three ratios to understand the relevance of each step in this mechanism. Regarding DP, it was concluded that direct oxidation by photogenerated holes is more important for the modified TiO2 materials (m-TiO2 and GOT-3.3) than for ECT and P25 which present higher availability to generate radical species from photoinduced holes. A photoreduction mechanism on the surface of the photocatalysts was observed for MO, the addition of EDTA (electron donor) greatly enhancing the rate of MO photoreduction.

18. Inorganic-organic core-shell titania nanoparticles for efficient visible light activated photocatalysis, N.G. Moustakas, A.G. Kontos, V. Likodimos, F. Katsaros, N. Boukos, D. Tsoutsou, A. Dimoulas, G.E. Romanos, D.D. Dionysiou, P. Falaras, Applied Catalysis B: Environmental, 130–131 (2013), 14–24. DOI: 10.1016/j.apcatb.2012.10.007

Abstract: Nanostructured modified TiO2 (m-TiO2) was synthesized using the gel combustion method based on the calcination of an acidified alkoxide solution mixed with urea. The materials were characterized by Raman, FT-IR and UV–vis diffuse reflectance spectroscopies, transmission (TEM) and scanning electron microscopies (SEM), X-ray photoelectron spectroscopy (XPS) and electron paramagnetic resonance (EPR), in comparison with reference material untreated with urea (ref-TiO2). The effect of both the urea content and calcination temperature were optimized, providing the optimal absorption threshold of 2.19 eV for solar light harvesting. The photocatalytic performance of the m-TiO2 powder was tested for the degradation of methylene blue (MB) azo dye under UVA (350–365 nm), visible (440–460 nm), and daylight (350–750 nm) illumination. The hybrid inorganic/organic material shows exceptional physicochemical properties and significant photocatalytic activity, especially in the visible, attributed to sensitization of the TiO2 by a thin porous layer of carbonacious species in controlled core–shell morphology.

19. Computational Intelligence-Based Identification of Maximally Sustainable Materials: the Case of Liquid Containers, Tambouratzis, T., Karalekas D., Moustakas N., 2013 IEEE Symposium Series on Computational Intelligence, IEEE SSCI 2013 16-19 April 2013, Singapore, 2013, pp. 102-109. DOI: 10.1109/CIES.2013.6611736

Abstract: A novel computational intelligence methodology is proposed for identifying the properties of maximally sustainable materials for any given application; identification is based on the known properties of existing candidate materials. Once the correlation surface between material properties and environmental impact values of the candidate materials is created via a general regression artificial neural network, genetic algorithms are used for accurately as well as efficiently determining the minimum/a of the correlation surface, thus uncovering the properties of the maximally sustainable material(s). A demonstration is given for a simplified type of material selection concerning maximally sustainable liquid containers. The proposed methodology is compared to and found more accurate than classic interpolation techniques; additionally, sensitivity and multi-criteria analyses confirm stability of the methodology under variations in both the material property values of the known materials and in the relative importance of the input properties. It is important that this methodology can be directly applied to a variety of material selection tasks by choosing the input properties of interest as well as the desired material selection criteria.

20. A Methodological Study for Optimizing Material Selection in Sustainable Product Design, Tatiana Tambouratzis, Dimitris Karalekas, Nikolaos G. Moustakas, Journal of Industrial Ecology, 18 (2013), 508-516. DOI: 10.1111/jiec.12035

Abstract: A computational intelligence-based identification of the properties of maximally sustainable materials for a given application, as derived from key properties of existing candidate materials, is put forward. The correlation surface between material properties (input) and environmental impact (EI) values (output) of the candidate materials is initially created using general regression (GR) artificial neural networks (ANNs). Genetic algorithms (GAs) are subsequently employed for swiftly identifying the minimum point of the correlation surface, thus exposing the properties of the maximally sustainable material. The ANN is compared to and found to be more accurate than classic polynomial regression (PR) interpolation/prediction, with sensitivity and multicriteria analyses further confirming the stability of the proposed methodology under variations in the properties of the materials as well as the relative importance values assigned to the input properties. A nominal demonstration concerning material selection for manufacturing maximally sustainable liquid containers is presented, showing that by appropriately picking the pertinent input properties and the desired material selection criteria, the proposed methodology can be applied to a wide range of material selection tasks.

Abstract: The fabrication of a power-free, reversible, color-indicator sensor of the relative humidity in the environment has numerous applications and is considered a challenging task. The device to be developed should be able of color changing according to the degree of humidity change and have a number of characteristics, i.e., reversibility, fast response, low cost, and, ideally, should be flexible. The proposed solution, based on a 1-D polymeric Photonic Crystal (PC) configuration on a microscope glass, can successfully fulfill all the above requirements.

Abstract: Nanocomposites of polyvinyl alcohol and ZnO were prepared using the solution casting method. ZnO nanoparticles with hexagonal wurtzite structure and mean sizes of 59, 82 and 150 nm were prepared by thermal decomposition of zinc acetate dihydrate. The synthesized crystals were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM). Optical properties of the nanocomposites were determined using UV–visible absorption spectroscopy. The results showed that all samples appeared near band edge absorption close to the bulk value. Furthermore, broadband dielectric spectroscopy, at ambient temperature, was employed in order to investigate the effect of mean particle size upon interfacial relaxation phenomena. Dielectric data provide evidence that interfacial polarization, which is present in all three nanocomposite films, shifts to higher frequencies and its intensity is decreasing as the mean nanoparticle diameter is also decreasing. Finally, exploiting the Cole–Davidson approach, becomes evident, that interfacial polarization process acquires a more symmetric form, tending to a pure Debye relaxation.
