Photocatalytic Activity of Zinc Oxide Based Heterostructures

Abstract

In this work we perform the study of photocatalytic activity of zinc oxide based heterostructures obtained by the low-temperature wet chemistry method. The structures were studied by atomic-force microscopy and it was found that the size of the particles varies from 50 nm to 150 nm. The photocatalytic activity of the heterostructures was studied using methyl orange organic dye that adsorbs light in visible region. The dye solution with photocatalyst loaded was irradiated with ultra-violet light and the concentration changes of the dye were monitored using UV-Vis spectrophotometer.
