摘　　要：电化学技术广泛用于工业废水的处理。电极材料是影响电化学处理效率的关键因素。因此目前的研究主要集中在对电极材料的开发制备与改性方面。主要从电絮凝、电氧化、电还原、电吸附作用机理来对电极材料进行分类,并介绍相关研究进展。电氧化阳极材料可分为基于吸附态和自由态·OH氧化原理的两类材料;而电还原阴极材料可分为基于直接还原和间接还原的两类材料。最后,对电极材料在水处理方面的发展方向进行了展望。Electrochemical technology is widely applied in the industrial wastewater treatment.Electrode material is a key factor affecting the efficiency of electrochemical treatment.Therefore,the current research mainly focuses on the development,preparation and modification of electrode materials.In general,this paper classifies electrode materials from the mechanisms of electroflocculation,electrooxidation,electroreduction and electroadsorption,and further introduces the relevant research progress.Anode materials can be divided into adsorbed and free·OH radical electrode materials,while cathode materials can be divided into direct reduction and indirect reduction materials.Finally,the development direction of electrode materials in the water treatment is prospected.
