摘要

Cu-Mn co-doped CeO2 photocatalyst was successfully synthesized by the sol-gel method to assess its capability in degrading tetracycline. XRD and TEM results showed that Cu and Mn were successfully co-doped into CeO2 without forming heterostructure, XPS and photoelectrochemical results revealed that Mn ions doping amplified the generation of photo-induced charge carriers, while Cu ions doping significantly facilitated the interfacial charge transfer process. Notably, the optimized Cu3Mn2CeO2 nanoparticles exhibited the highest TC removal efficiency, achieved a rate of 78.18% and maintained a stable cycling performance.
