摘　　要：从废水处理的角度,探讨了废水处理用催化电极研究中存在的问题并对有代表性的电极材料进行了评价。认为电催化法与普通电化学法的主要区别是能够通过电催化产生.OH来氧化降解废水中的有机污染物,其技术关键是电极材料的催化活性。讨论了目前正在研究开发的金属电极、碳素电极、金属氧化物电极、非金属氧化物电极、粒子电极等取得的进展,指出尚未解决的问题和发展方向。The problem of catalytic electrodes for water treatment are reviewed and some representative catalytic electrodes are evaluated in this paper. It is held that the difference between eleetroeatalytic method and electrochemistry method is that the former can produce OH radical to oxidize organic pollutants in wastewater and the catalytic activity of anode materials is principal performance. The recent progress in metal electrodes, carbon electrodes, metal oxide electrodes, non-metal oxide electrodes, particle electrodes in the study was discussed and unsettled problem and developing direction of them were pointed out.
