摘　　要：本文以硝酸银和磷酸为原料,控制不同条件通过液相化学反应获得Ag3PO4晶体。采取XRD、SEM、UV-vis等手段对样品进行表征,并探究其光催化性能。研究表明:不同条件对Ag3PO4的形貌有一定的影响,搅拌条件下制备出的四面体Ag3PO4具有最佳的光催化降解亚甲基蓝性能,24 min内降解率达到96%,对RhB和MO的降解率均为85%以上,加大催化剂用量光催化时间明显缩短,这主要归因于电荷在Ag3PO4中良好的传输性能。Ag3PO4 crystals were obtained by a simple liquid phase chemical method using silver nitrate and phosphoric acid as raw materials.The samples were characterized by XRD,SEM,UV-vis methods and the photocatalytic activity was evaluated.Results showed that different experimental prepa-ration conditions had a certain influence on the morphology of Ag3PO4.Tetrahedral Ag3PO4 under stirring has high photocatalytic degradation of 96%within 24 min for MB,and above 85%for RhB and MO.Photocatalytic time was obviously shortened with increasing Ag3PO4,which was due to good transport performance of the charge.
