摘要： 采用氨水做给合剂制备出立方体Ag3PO4后，用葡萄糖作还原剂制备了Ag3PO4/Ag复合材料。通过X射线衍射、扫描电子显微镜等来研究样品的结构与形貌，并对Ag3PO4/Ag的光催化性能做了初步探索。结果表明：在葡萄糖还原过程中，加入氨水，纳米银颗粒负载在磷酸银颗粒的表面；而不加氨水，则负载在磷酸银颗粒的棱上。可见光催化研究表明：Ag3PO4/Ag复合材料具有可见光催化性能，并且银颗粒负载在磷酸银表面时光催化性能较好。

Abstract: In this paper, cubic Ag3PO4 was prepared by ammonia as complexing agent, and then Ag3PO4/Ag composite particles were prepared by glucose as reducer. The structure and morphology of the samples was characterized by SEM, XRD, and the photocatalytic activity of Ag3PO4/Ag was preliminarily explored. The results showed that adding the ammonia made the Ag nanoparticles supported on the surface of Ag3PO4 particles in reduction of glucose, but the Ag nanoparticles were loaded on the edge of Ag3PO4 particles. The research of visible photocatalysis showed Ag3PO4/Ag composites had the visible light photocatalytic properties and Ag nanoparticles loaded on the surface of Ag3PO4 showed the better photocatalytic property.
