摘要
以SrFe12O19为磁基体,钙钛矿SrFeO3-x为光催化剂,用不同方法制备了磁载复合光催化剂SrFeO3-x/SrFe12O19,通过光催化降解亚甲基蓝实验,发现溶胶复合方法制备的磁载光催化剂光催化性能较好。通过调节SrFeO3-x/Sr-Fe12O19的质量比,发现随着SrFeO3-x含量的增大,所得磁载光催化剂光催化活性逐渐增强,但磁性逐渐减弱。
Using SrFe12O19 as magnetite and perovskite-typed SrFeO3-x as photocatalyst,a series of composites of SrFeO3-x/SrFe12O19 were prepared by various methodologies.In methylene blue decomposition as test reaction,it was found that the composites prepared via sol-mixing process possessed superior photocatalytic performance.Furthermore,an increase of SrFeO3-x content in the composites led to elevated photocatalytic activity and decreased magnetism.
