DLNTs were annealed at 700 °C in ambient atmosphere for different times. ZnAl2O4 phase formed due to solid-state reaction. To follow the growth kinetics of the spinel, thin lamellae were prepared from the cross sections of the tubes and studied in a transmission mode scanning electron microscope (TSEM). The phase grows parabolically with time, independently of the layer sequence. The growth rate was higher in the )ZnO)AlO) layer sequence, than for the reverse case. This can be explained by the competing vacancy fluxes induced by mechanical stress developing during the solid-state reaction and by the difference in the diffusion fluxes of the two constituents. This is the first case that the influence of closed geometry and layer sequence on spinel growth between two oxide layers has been experimentally investigated.}, year = {2023}, eissn = {2589-1529}, orcid-numbers = {Tomán, János/0000-0003-3374-0147} } @article{MTMT:34023694, title = {Investigating the Reduction/Oxidation Reversibility of Graphene Oxide for Photocatalytic Applications}, url = {https://m2.mtmt.hu/api/publication/34023694}, author = {Bakos, László Péter and Bohus, Marcell and Szilágyi, Imre Miklós}, doi = {10.3390/molecules28114344}, journal-iso = {MOLECULES}, journal = {MOLECULES}, volume = {28}, unique-id = {34023694}, issn = {1420-3049}, year = {2023}, eissn = {1420-3049} } @article{MTMT:33797577, title = {Bismuth oxychloride microcrystals decorated carbon foams based on waste polyurethane elastomer for enhanced removal of methylene blue}, url = {https://m2.mtmt.hu/api/publication/33797577}, author = {Udayakumar, Mahitha and Sharma, Nikita and Hernádi, Klára and Finšgar, Matjaž and Likozar, Blaz and Kocserha, István and Leskó, Máté Zsigmond and Karajz, Dániel Attila and Szilágyi, Imre Miklós and Németh, Zoltán}, doi = {10.1016/j.jphotochem.2023.114812}, journal-iso = {J PHOTOCH PHOTOBIO A}, journal = {JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY A-CHEMISTRY}, volume = {443}, unique-id = {33797577}, issn = {1010-6030}, year = {2023}, eissn = {1873-2666}, orcid-numbers = {Hernádi, Klára/0000-0001-9419-689X; Németh, Zoltán/0000-0001-7871-3818} } @article{MTMT:33752929, title = {Synthesis of TiO2/Al2O3 Double-Layer Inverse Opal by Thermal and Plasma-Assisted Atomic Layer Deposition for Photocatalytic Applications}, url = {https://m2.mtmt.hu/api/publication/33752929}, author = {Lemago, Hamsasew Hankebo and Addin, Feras Shugaa and Karajz, Dániel Attila and Igricz, Tamás and Parditka, Bence and Erdélyi, Zoltán and Hessz, Dóra and Szilágyi, Imre Miklós}, doi = {10.3390/nano13081314}, journal-iso = {NANOMATERIALS-BASEL}, journal = {NANOMATERIALS}, volume = {13}, unique-id = {33752929}, abstract = {In comparison to conventional nano-infiltration approaches, the atomic layer deposition (ALD) technology exhibits greater potential in the fabrication of inverse opals (IOs) for photocatalysts. In this study, TiO2 IO and ultra-thin films of Al2O3 on IO were successfully deposited using thermal or plasma-assisted ALD and vertical layer deposition from a polystyrene (PS) opal template. SEM/EDX, XRD, Raman, TG/DTG/DTA-MS, PL spectroscopy, and UV Vis spectroscopy were used for the characterization of the nanocomposites. The results showed that the highly ordered opal crystal microstructure had a face-centered cubic (FCC) orientation. The proposed annealing temperature efficiently removed the template, leaving the anatase phase IO, which provided a small contraction in the spheres. In comparison to TiO2/Al2O3 plasma ALD, TiO2/Al2O3 thermal ALD has a better interfacial charge interaction of photoexcited electron–hole pairs in the valence band hole to restrain recombination, resulting in a broad spectrum with a peak in the green region. This was demonstrated by PL. Strong absorption bands were also found in the UV regions, including increased absorption due to slow photons and a narrow optical band gap in the visible region. The results from the photocatalytic activity of the samples show decolorization rates of 35.4%, 24.7%, and 14.8%, for TiO2, TiO2/Al2O3 thermal, and TiO2/Al2O3 plasma IO ALD samples, respectively. Our results showed that ultra-thin amorphous ALD-grown Al2O3 layers have considerable photocatalytic activity. The Al2O3 thin film grown by thermal ALD has a more ordered structure compared to the one prepared by plasma ALD, which explains its higher photocatalytic activity. The declined photocatalytic activity of the combined layers was observed due to the reduced electron tunneling effect resulting from the thinness of Al2O3.}, year = {2023}, eissn = {2079-4991}, orcid-numbers = {Erdélyi, Zoltán/0000-0003-0364-7996; Hessz, Dóra/0000-0003-3033-2762} } @article{MTMT:33589712, title = {Good laboratory practice in thermal analysis and calorimetry}, url = {https://m2.mtmt.hu/api/publication/33589712}, author = {Verma, Ranjit K. and Szilágyi, Imre Miklós and Pielichowska, Kinga and Raftopoulos, Konstantinos N. and Šimon, Peter and Melnikov, Alexey P. and Ivanov, Dimitri A.}, doi = {10.1007/s10973-022-11877-5}, journal-iso = {J THERM ANAL CALORIM}, journal = {JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY}, volume = {-}, unique-id = {33589712}, issn = {1388-6150}, year = {2023}, eissn = {1572-8943}, pages = {x}, orcid-numbers = {Verma, Ranjit K./0000-0001-9595-7179} } @article{MTMT:33429225, title = {Demonstration of effectiveness: plant extracts in the tuning of BiOX photocatalysts' activity}, url = {https://m2.mtmt.hu/api/publication/33429225}, author = {Sharma, Nikita and Saszet, Kata and Szabó, Tamás and Karajz, Dániel Attila and Szilágyi, Imre Miklós and Garg, Seema and Pap, Zsolt and Hernádi, Klára}, doi = {10.1016/j.cattod.2022.12.015}, journal-iso = {CATAL TODAY}, journal = {CATALYSIS TODAY}, volume = {413-415}, unique-id = {33429225}, issn = {0920-5861}, year = {2023}, eissn = {1873-4308}, orcid-numbers = {Pap, Zsolt/0000-0002-8049-0809; Hernádi, Klára/0000-0001-9419-689X} }
