摘　　要：持久性含氯有机污染物严重威胁生态安全和人类健康。电催化加氢脱氯技术作为一种安全、绿色、高效的水处理技术受到广泛关注。Pd是电催化还原脱氯过程的经典催化剂,但其成本高、易中毒失活。开发高效、廉价、稳定的新型电极材料是当前的研究热点。简述了还原脱氯机理,综述了构建复合材料、元素掺杂、吸脱附调控、仿生设计等催化剂设计策略,讨论了污染物浓度、溶液酸碱性、溶液共存离子、工作电位等对脱氯性能的影响。研究表明,通过调控负载型催化剂界面强相互作用,优化电子结构和反应微环境,强化废水中低浓度含氯有机物在催化剂周围的富集行为,有利于构建高效电化学还原加氢脱氯体系。同时,本文也初步指出了该技术发展面临的问题及未来的研究方向。Persistent chlorinated organic pollutants pose a serious threat to ecological security and human health.Electrocatalytic hydrogenation dechlorination technology as a safe,green and efficient water treatment technology has been widely researched.Pd is a classic catalyst in electrocatalytic reduction dechlorination process,but it is costly and easy to be poisoned.Developing high efficiency,low cost and stable new electrode materials is the current research hotspot.In this paper,the mechanism of reduction dechlorination is briefly described,the design strategies of catalysts such as composite construction,element doping,absorption and desorption regulation,bionic design are reviewed,and the effects of pollutant concentration,pH,co-existing ions in solution,and working potential on dechlorination performance are also discussed.Studies have shown that regulating the strong interfacial interaction of supported catalysts,optimizing the electronic structure and reaction microenvironment,and strengthening the enrichment behavior of low concentration chlorine-containing organic matter in wastewater around the catalyst,are beneficial to build an efficient electrochemical reduction hydrodechlorination system.At the same time,this paper also preliminarily points out the problems faced by the development of this technology and the future development direction.
