摘　　要：采用水热合成法制备出CaSnO3/膨润土复合光催化剂,采用XRD、SEM和IR等分析手段对该样品的形貌和结构进行表征,并研究了其对亚甲基蓝水溶液的光催化降解性能.结果表明:负载比例为3%的CaSnO3/膨润土复合光催化剂对亚甲基蓝水溶液的降解效果最好,当催化剂用量为60 mg,反应时间为14 min时,降解率可达98%.CaSnO3/bentonite compound photocatalysts were synthesized by hydrothermal synthesis method. The formation and microstructure of samples were characterized by XRD, SEM and IR. Its photocatalytic activity on methyl blue was also investigated. The results indicated that The photo-degradation efficiency could reach 98% when the load- ing contents were 3% , the amount of photoeatalysts was 60 mg and the reaction time was 14 rain.
