摘　　要：通过简单的研磨-焙烧的方法制备了不同质量比的复合型光催化剂CaFe2O4/Bi2WO6,并进行了表征。以亚甲基蓝水溶液的光催化降解为探针反应,考察了所制备复合光催化剂的光催化活性。同时,还考察了焙烧温度、H2O2的加入对光催化降解活性的影响。结果表明,所制备复合光催化剂具有较高的催化活性,良好的稳定性和重复使用性。Composite of CaFe2O4/Bi2WO6 with different mass ratio was synthesized using a simple mixing-annealing method and characterized by various method. The photocatalytic activities of the samples were investigated in degradation of methylene blue （MB） under simulated s t and the effects of calcination temperature also investigated. The samples had shown excellent performances in degradation of methylene and recyclability. and addition of H2O2 were blue and prominent stability
