【Abstract】 The persistence and resistance to degradation of antibiotic wastewater pose a serious threat to human health and the ecological environment. Electrocatalytic oxidation has emerged as an effective approach to address the challenge of recalcitrant antibiotic wastewater. This study focuses on three representative antibiotics, i.e., fluoroquinolones, amphenicols and tetracyclines, and systematically reviews their degradation mechanisms. Additionally, it delves into the current strategies for modifying electrode materials used in the electrocatalytic treatment of recalcitrant antibiotic wastewater. These strategies primarily include introducing intermediate layers to optimize charge transfer, doping with metal elements to enhance catalytic activity, and incorporating metal oxides and non-metallic materials to improve electrode stability and selectivity. These modifications have significantly improved the catalytic activity and overall efficiency of electrocatalytic reactions. Finally, the paper provides an outlook on the development directions and application prospects of three-dimensional electrocatalytic systems, novel carbon-based composites, metal oxides and nanostructured electrode materials, aiming to offer systematic guidance and reference for both fundamental theoretical research and industrial engineering application of electrocatalytic technology in antibiotic wastewater remediation.更多还原
