ОPTICAL AND STRUCTURAL PROPERTIES OF ZnO-BASED PHOTOCATALYSTS

Abstract

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.
