Гидротермальным методом синтезирован нанокомпозит на основе оксида графена и TiO2. Образование нанокомпозита было подтверждено данными Раман-спектроскопии. В Раман-спектрах зарегистрированы характерные пики оксида графена и TiO2. ЭДС анализ показал присутствие титана, углерода и кислорода в нанокомпозите. Удельная площадь поверхности нанокомпозита TiO2-GO в 1,16 раз больше, чем для TiO2. Проведено исследование фотокаталитической активности синтезированного материала в электролитах с различным уровнем рН. Показано, что генерация фототока в TiO2–GO зависит от электролита и возрастает в 2,9, 1,3 и 1,05 раза в NaOH, KOH и Na2SO4, соответсвенно, по сравнению с пленками чистого TiO2.
