Abstract: Using ZnO powders , Na2 HPO4 , AgNO3 and polyvinylpyrrolidone as raw materials , Ag3 PO4/ZnO composite powders were successfully prepared at room temperature .The phase structure , morphology and adsorption of visible-light of composites with various ratios of ZnO and Ag 3 PO4 were characterized by X ray diffraction, scanning electron microscopy and UV spectrometer .The photocatalytic activity of corresponding Ag 3 PO4/ZnO composite powders was also investigated . The results show that the performance of photocatalytic degradation of rhodamine B is excellent ( the degradation rate is 99;or so ) when the molar ratio of ZnO and Ag 3 PO4 is about 1:1.
