For the formation of such structures with titanium dioxide the strontium titanate SrTiO3 is used. In this work, a technique for producing TiO2/SrTiO3 composites formed by nanocubes of strontium titanate on the surface of filamentous TiO2, in order to improve its photocatalytic activity, is described. Nanocubic SrTiO3 was obtained from eight-way strontium hydroxide Sr(OH)2×8H2O and hydrogen titanate H2Ti3O7 during a two-stage hydrothermal reaction. A technique for forming a TiO2/SrTiO3 composite layer on a titanium foil substrate for studies of photocatalytic properties by gas chromatography is described. The results of a study of the morphology of TiO2/SrTiO3 nanostructures by scanning electron microscopy and the phase composition of samples by X-ray diffraction analysis depending on the synthesis temperature and post-treatment temperature are presented. The results of measuring the optical band gap of the TiO2/SrTiO3 composite obtained by diffuse reflection spectroscopy are given. Based on the values of the component yields, the results of a study of the catalytic activity of samples in the carbon dioxide CO2 reduction reaction are described. The results have shown that the total yield of reaction products increased by three times using the TiO2/SrTiO3 composite compared to commercial TiO2 P25.</p></abstract><trans-abstract xml:lang="ru"><p>Повышение фотокаталитической активности диоксида титана TiO2 путем формирования композитов с полупроводниками типа перовскита – актуальная проблема в технологии полупроводникового фотокатализа. Для образования подобных структур с TiO2 используется титанат стронция SrTiO3. В работе описана методика получения композитов TiO2/SrTiO3, образованных нанокубами SrTiO3 на поверхности нитевидного TiO2 в целях улучшения его фотокаталитической активности. Нанокубический SrTiO3 получен из восьмиводного гидроксида стронция Sr&amp;#40;OH&amp;#41;2×8H2O и титаната водорода H2Ti3O7 в ходе двухстадийной гидротермальной реакции. Описана методика формирования слоя компо-зита TiO2/SrTiO3 на подложку из титановой фольги для исследований фотокаталитических свойств методом газовой хроматографии. Представлены результаты исследования морфо-логии наноструктур TiO2/SrTiO3 методом растровой электронной микроскопии и фазового состава образцов методом рентгенофазового анализа в зависимости от температуры синтеза и температуры постобработки. Приведены результаты измерения оптической ширины запрещенной зоны композита TiO2/SrTiO3, полученные методом спектроскопии диффузного отражения. На основе значений выхода компонентов описаны результаты исследования фотокаталитической активности образцов в реакции восстановления диоксида углерода CO2. Результаты показывают, что общий выход продуктов реакции увеличился в три раза с использованием композита TiO2/SrTiO3 по сравнению с коммерческим диоксидом титана TiO2 P25.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диоксид титана TiO2</kwd><kwd>титанат стронция SrTiO3</kwd><kwd>диоксид углерода CO2</kwd><kwd>гидротермальный синтез</kwd><kwd>нанонити</kwd><kwd>фотокаталитическая активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanium dioxide TiO2</kwd><kwd>strontium titanate SrTiO3</kwd><kwd>carbon dioxide CO2</kwd><kwd>hydrothermal synthesis</kwd><kwd>nanoscale filaments</kwd><kwd>catalytic activity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при финансовой поддержке Российского научного фонда (проект № 22-19-00654).</funding-statement><funding-statement xml:lang="ru">the work has been supported by the Russian Science Foundation (project no. 22-19-00654).</funding-statement></funding-group></article-meta>
