Abstract

Ag modified TiO 2 loaded on artificial zeolites was prepared by sol-gel technique and photoreductive deposition method. The photocatalytic activities were investigated by the photocatalytic decolorization of methyl orange solution under visible light irradiation. The results show that Ag doping induced the enhancement of photocatalytic decolorization methyl orange and the optimal Ag/Ti mole ratio was 0.03. TiO 2 doping ratio is 35.16% in mass ratio. The effects of calcinated temperature on the photocatalytic activities were studied. When calcinated temperature was 400 °C, the photocatalyst showed the best photocatalytic activities.
