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.

 

Optical, structural and catalytic properties of Al-dopped ZnO-based photocatalysts were investigated. The hydrothermal synthesis was used to synthesize the catalysts. Dielectric barrier discharge plasma was applied to treat the synthesized samples. The performance of plasma-treated and untreated catalysts was compared with that of commercially available catalysts. The photocatalytic activity, expressed in terms of the rate of photodegradation of methyl orange, was 3.6 times higher for synthesized samples than that for commercial catalyst. The photocatalytic activity was up to 60 % higher for the plasmatreated samples than for the untreated ones.
