： 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
