摘要：

Commercial TiO2 (P25) doped with metallic silver nanoparticles was prepared by gamma-irradiation method. The size of silver nanoparticles (AgNPs) was determined by transmission electron microscopy (TEM) to be of 1-2 nm. The photo-catalytic degradation of azo dye Metyl Red (MR) in the aqueous suspensions of TiO2 and Ag/TiO2 under visible light was carried out to evaluate the photo-catalytic activity. Results showed that Ag/TiO2 was found to enhance higher photo-degradation efficiency of Metyl Red (72%) than those of commercial P25-TiO2 (23%). Thus, gamma-irradiation method can be suitably applied to prepare photo-catalyst of TiO2 doped with siver nanoparticles with highly photo-catalytic activity under visible light.
