Abstract

Abstract:

： Zinc tungstate（ZnWO₄） powder was synthesized by hydrothermal method. Ag₃PO₄ was aggregated on the surface of ZnWO₄ by in situ precipitation,resulting in formation of ZnWO₄/Ag₃PO₄ composite photocatalyst.Effect of Ag₃PO₄ content on photocatalytic performance of ZnWO₄/Ag₃PO₄ was investigated by photocatalytic degradation of Rhodamine B.The results showed that the photocatalytic performance of ZnWO₄/Ag₃PO₄ composites was better than that of the photocatalyst with single material when the mass fraction of Ag₃PO₄ was over 40%.The photocatalytic performance of the composites with Ag₃PO₄ mass fraction of 50% was the best,and the photocatalytic efficiency remained over 90% after five cycles.

Key words: zinc tungstate, silver phosphate, photocatalysis, Rhodamine B
