As the most promising techniques for refractory antibiotic degradation in wastewater management, sulfate radical-based advanced oxidation processes (SR-AOPs) have attracted considerable attention. However, systematic studies on potassium peroxymonosulfate (PMS) activation by MOF-derived metal oxides coated with LDH materials are still lacking. In this work, a series of catalysts consisting CoCu-MOFs CuAl/LDH were synthesized PMS removal sulfamethoxazole (SMX). expected, catalyst showed high SMX and stability activation. CoCu/LDH/PMS reaction, was nearly 100% after 60 min, mineralization reached 53.7%. The excellent catalytic low leaching concentrations (Co: 0.013 mg/L, Cu: 0.313 mg/L), as detected ICP. Sulfate radicals hydroxyl identified dominant reactive species system. Moreover, presence 1O2 process revealed coupling non-radical radical processes. XPS results that layered structure CoCu/LDH promoted recycling ions (high valence), which facilitated heterogeneous effects different reaction conditions reuse cycles also determined. pathways proposed based intermediates LC/MS. activity provide new mechanistic understanding their potential utilization practical treatment.
