摘要
地下水和地表水的硝酸盐污染日益严重,威胁着人类健康和生态系统,已成为亟待解决的环境问题之一.电催化还原作为一种绿色环保、无二次污染的技术,能够将硝酸盐转化为无毒无害的氮气,具有良好的应用前景.在电催化还原硝酸盐体系当中,电极材料是电化学反应的关键,在过去几十年里,许多学者在设计和制备高效的电极方面做了大量研究.本文介绍了电催化还原处理硝酸盐技术的基本原理和降解路径,重点讨论了国内外电催化还原处理硝酸盐所用的不同电极材料,总结了不同电极材料的应用现状,并对电催化还原硝酸盐技术未来的发展方向提出了展望.
The nitrate pollution of groundwater and surface water is becoming more and more serious,which threatens human health and ecosystem,and has become one of the environmental problems to be solved urgently.Electrocatalytic reduction as a kind of green environmental protection technology,no secondary pollution to convert nitrate into non-toxic harmless nitrogen gas,has a good application prospect.In the electrocatalytic reduction of nitrate system,electrode material is the key to the electrochemical reaction.In the past decades,many scholars have done a lot of research on the design and preparation of efficient electrode.In this paper,the basic principle and degradation path of electrocatalytic reduction of nitrate are introduced,and the different electrode materials used in electrocatalytic reduction of nitrate at home and abroad are emphatically discussed.The application status of different electrode materials is summarized,and the development direction of electrocatalytic reduction of nitrate in the future is prospected.
