摘　　要：采用人工合成的金刚石膜电极进行电化学氧化降解处理污染物的探索工作,已成为环境电化学领域中最为关注的国际性研究热点之一。从电催化氧化降解技术处理污染物的研究现状及其存在的问题出发,分析了适用于污染物降解处理的高效电极材料应具有的表面特性及其电化学性质。在综述了金刚石膜电化学研究以及应用于污染物处理的工作基础上,结合近期相关的研究结果,论述了金刚石膜电极的电化学特性以及对污染物氧化降解的应用和降解机理。金刚石膜电极将是未来环保处理中非常适用、高效、稳定的电极材料。The exploring work of using the synthetic diamond film electro de to degrade pollutants through electrochemical oxidation technology has become one of the most concerned research hot spots in the environmental electrochemis try fields. Aiming at the research actuality and problems of electrocatalytic ox idative technics for pollutants degradation, the surface structure and behavior s of the highly efficient electrode materials suitable for the pollutants degrad ation have been analysed. On the basis of the summarization of the electrochemic al research for diamond film electrode and its application to pollutants degrada tion, some correlative experiments have been performed. Not only the electroche mical behaviors of diamond electrode but also its feasibility for pollutants deg radation and degradative mechanism have been discussed. Diamond film electrode w ill be a kind of stable electrode material with high efficiency for environmenta l treatment.
