摘要：A series of Ag-doped TiO2 powder photocatalysts were prepared by the sol-gel method. The phase structure and morphology of the samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The persistent organic pollutant sodium pentachlorophenol ate (PCP-Na) was selected as the target pollutant, and the photocatalytic property of the material Ag/TiO2 was evaluated by PCP-Na degradation rate. It was found that the calcination at 450 °C was conducive to form the anatase structure with high catalytic activity, and the catalytic activity was higher when the silver mole fraction of Ag/TiO2 was 0.50%. The influence of Ag/TiO2 dosage, hydrogen peroxide volume, silver mole fraction and PCP-Na initial concentration was investigated by the single factor experiment.
