Abstract

A simple strategy for synthesizing Ag decorated TiO2/WO3 composite nanoparticles by sol-gel method used as recyclable photocatalyst is introduced. The photocatalytic efficiency to the degradation of methyl blue (MB) by Ag/TiO2/WO3 nanoparticles is studied under ultraviolet-visible (UV-Vis) light irradiation. It shows that the photocatalytic efficiency of Ag/TiO2/WO3 photocatalyst achieves 96% in 20 min, which is 16 times higher than that of pristine TiO2 at the same conditions. The Ag/TiO2/WO3 photocatalyst can still reach the degradation rate of 90% in the fifth degradation experiment, indicating a good stability and photocatalytic activity.
