摘　　要：利用简单沉积法制备Fe-ZIF@MOF异质结构材料,在氮气环境下,将该材料煅烧成Ti-Fe-O@C的片状复合材料,并在light/PMS体系下对有机染料进行降解,结果表明:该复合材料的特殊结构能在仅30 min内将模拟废水罗丹明B(RhB)几乎完全降解,降解率能够达到99%以上。Fe-ZIF@MOF heterostructure materials were prepared by simple deposition method.The materials were calcined into Ti-Fe-O@C lamellar composites in nitrogen environment,and the organic dyes were degraded under light/PMS system.The results showed that:the special structure of the composite material can almost degrade the simulated wastewater Rhodamine B(RhB)in only 30 minutes,and the degradation rate can reach more than 99%.
