摘要

Developing efficient and cost-effective heterogeneous catalysts remains a significant challenge in environmental remediation. In this study, a novel MIL-88B(Fe)@CuS composite catalyst was synthesized using a simple solvothermal method, and the catalyst was comprehensively characterized using PXRD, FE-SEM, TEM, FT-IR, XPS, BET, and EIS. The study investigated the effects of various factors on tetracycline (TC) degradation, including catalyst concentration, TC concentration, PDS dosage, initial pH, reaction temperature, and inorganic anions. Based on EPR, XPS, and HPLC–MS tests, the reaction mechanism and possible degradation pathway of TC degradation in MIL-88B(Fe)@CuS(1:1)/PDS system were elucidated.
