摘要

采用水热法合成钨酸锌(ZnWO4)粉体,再通过原位沉淀法将磷酸银(Ag3PO4)聚集于ZnWO4表面制备ZnWO4/Ag3PO4复合光催化剂。通过罗丹明B光催化降解实验,探讨Ag3PO4含量对ZnWO4 /Ag3PO4材料光催化性能的影响。结果表明,当复合粉体中Ag3PO4质量分数超过40%时,其光催化性能比单一成分的Ag3PO4催化剂更优。Ag3PO4质量分数为50%时,复合材料的光催化性能最佳,循环使用5次后其光催化效率仍可达到90%以上。

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.
