Boosting Photocatalytic Performance of Cu-Mn Co-doped CeO₂ Nanoparticles for Tetracycline Degradation

Abstract

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.
