Abstract
Nano-ZnO was prepared by sol-gel method. Silver chloride was loaded onto the ZnO particles by a precipitation reaction, and some of the AgC1 particles were reduced to Ag particles under halogen tungsten lamp irradiation. The structure of Ag@AgCl-modified ZnO was characterized by XRD, TEM and XPS. It’s photocatalytic activity was investigated by the photocatalytic degradation of methyl orange. The results show that the size of as prepared ZnO particles is 20-30 nm as photocatalytic agent, Ag@AgCl/ZnO composite has better photocatalytic activity of visible light and can degrades the methyl orange effectively under visible light irradiation.
