ОПТИЧЕСКИЕ И СТРУКТУРНЫЕ СВОЙСТВА ФОТОКАТАЛИЗАТОРОВ НА ОСНОВЕ ZnO

Исследованы оптические, структурные и каталитические свойства допированных атомами алюминия (Al) фотокатализаторов на основе оксида цинка (ZnO), которые получены методом гидротермального синтеза. Проведено сравнение каталитической активности синтезированных фотокатализаторов до и после обработки в плазме диэлектрического барьерного разряда с активностью промышленно полученного порошка ZnO. Показано, что эффективность реакции фотодеградации метилового оранжевого (МО), выраженная в терминах константы реакции МО, для синтезированных фотокатализаторов выше в 3,6 раза, чем для промышленного образца, и увеличивается приблизительно на 60 % после обработки фотокатализаторов в плазме.
