摘　　要：采用共沉淀法制备出完整的立方相锡酸铅纳米粒子,并研究了其对甲基橙溶液的光催化降解性能。结果表明:PbSnO3催化剂对甲基橙溶液有良好的光催化降解效果。当催化剂用量为60mg/L,反应时间为80min时,降解率可达90%以上。The cubic PbSnOa nanoparticles were prepared by a co-precipitation method. The photocatalytic activity of nanoparticles on methylene Orange was also investigated. When the catalysts of PbSnO3 nanopartieles were irradiated by the visible light, the photo-degradation of methylene orange courd reachover 90% as the concention of photocatalysts was 60 mg/L and the reaction time was 80min.
