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.
