| 摘 要： | 采用水热合成法，在绢云母表面沉淀一层氧化铁薄膜，制备成氧化铁/绢云母复合光催化剂。并以次甲基蓝为降解物，重点探讨了催化剂后处理方式、体系H2O2浓度和催化剂添加量对光催化效率的影响。结果证明，复合光催化剂煅烧前比煅烧后降解效果更好；体系H2O2浓度为0.5%、光催化剂用量为5 g/L时，降解效果最佳。

| Abstract: | The ferric oxide/sericite compound photocatalyst was prepared with precipitating ferric oxide on the surface of sericite by hydrothermal synthesis, and used as the photocatalyst for the degradation of methylene blue. The effects of catalyst treatment method, the H2O2 concentration and the amount of catalyst on the photocatalytic degradation efficiency were researched. The results proved that the degradation efficiency of the compound photocatalyst was better when the H2O2 concentration was 0.5 % and the amount of catalyst was 5 g/L. |
