Фотокаталитическая активность гранулированных композитных оксидов TiO2/SiO2 в реакциях деструкции красителей
Аннотация
В данной работе исследованы фотокаталитические свойства композитных гранулированных фотокатализаторов, в которых наноразмерные фотокаталитически активные частицы на основе анатаза внедрены в объём гранулы силикагеля. Показано, что композитные гранулы успешно окисляют модельные органические загрязнения – красители метиленовый голубой, метиловый оранжевый и метиловый фиолетовый.
