    • Water Splitting on Multifaceted SrTiO3 Nanocrystals: Calculations of Raman Vibrational Spectrum 

      Krasnenko, Vera; Rusevich, Leonid L.; Platonenko, Aleksander; Mastrikov, Yuri A.; Sokolov, Maksim; Kotomin, Eugene A. (MDPI, 2022)
      Various photocatalysts are being currently studied with the aim of increasing the photocatalytic efficiency of water splitting for production of hydrogen as a fuel and oxygen as a medical gas. A noticeable increase of ...

    • Water Splitting on Multifaceted SrTiO3 Nanocrystals: Computational Study 

      Sokolov, Maksim; Mastrikov, Yuri A.; Zvejnieks, Guntars; Bocharov, Dmitry; Kotomin, Eugene A.; Krasnenko, Veera (Multidisciplinary Digital Publishing Institute (MDPI), 2021)
      Recent experimental findings suggest that strontium titanate SrTiO3 (STO) photocatalytic activity for water splitting could be improved by creating multifaceted nanoparticles. To understand the underlying mechanisms and ...

    • WO3 as Additive for Efficient Photocatalyst Binary System TiO2/WO3 

      Knoks, Ainars; Kleperis, Janis; Bajars, Gunars; Grinberga, Liga; Bogdanova, Olga (Walter de Gruyter, 2021)
      Two different methods of synthesis of TiO2/WO3 heterostructures were carried out with the aim to increase photocatalytic activity. In this study, anodic TiO2 nanotube films were synthesized by electrochemical anodization ...

    • X-ray absorption and Raman spectroscopy studies of tungstates solid solutions ZncNi1-cWO4 (c=0.0-1.0) 

      Bakradze, Georgijs; Kalinko, Aleksandr; Kuzmin, Alexei (AIP Publishing, 2020)
      The influence of thermal disorder and static distortions on the local structure in microcrystalline solid solutions of tungstates ZncNi1-cWO4 with c = 0.0–1.0 was investigated using temperature-dependent (10–300 K) x-ray ...

    • X-ray absorption near edge spectroscopy of thermochromic phase transition in CuMoO4 

      Jonane, Inga; Cintins, Arturs; Kalinko, Aleksandr; Chernikov, Roman V.; Kuzmin, Alexei (Institute for Low Temperature Physics and Engineering, 2018)
      Thermochromic phase transition was studied in CuMoO4 using the Cu and Mo K-edge x-ray absorption spec-troscopy in the temperature range of 10-300 K. The hysteretic behavior has been evidenced from the tempera-ture dependence ...
