摘　　要：采用湿化学法制备不同摩尔比的Ag/AgCl/SnO_2复合光催化剂,并通过X射线粉末衍射和扫描电子显微镜对其组成与形貌结构进行表征.研究发现Ag/AgCl纳米颗粒均匀负载在SnO_2微米片上.以500 W氙灯为光源,以罗丹明B为目标降解物,光催化活性实验结果表明2:1Ag/AgCl/SnO_2复合光催化剂表现出最强的光催化活性,并具有较好的光催化稳定性.Ag/AgCl/SnO_2 composite photocatalysts with different mole ratio were synthesized via wet chemical method. The obtained products were characterized by X-ray powder diffraction（XRD） and scanning electron microscope（SEM） on the composition and morphology structure, showing Ag/AgCl nanoparticles were dispersed on the surface of SnO_2 nanoplates uniformly.The photocatalytic activity of Ag/AgCl/SnO_2 were studied by degradation of Rh B under 500 W Xe light irradiation, which demonstrated that 2：1 Ag/AgCl/SnO_2 showed the highest photocatalytic activity in degradation of Rh B solution. What＇s more it had excellent stability.
