摘　　要：A sustainable nitrogen fixation industrial chain centered around nitrate has been proposed in recent years,incorporating advanced techniques such as electro/photocatalytic nitrate reduction for ammonia and the co-reduction of nitrate and CO2 for urea production.However,nitrate production heavily relies on energy-intensive processes,which necessitate high-temperature and high-pressure conditions,leading to significant energy consumption and greenhouse gas emissions.So,electrocatalytic nitrogen oxidation is receiving increasing attention as a novel pathway for nitric acid production.Herein,we summarize the recent developments of N2 oxidation reactions with a focus on their design,mechanism,and catalytic kinetics regulation.Based on the results discussed,we briefly present the current challenges and propose several future opportunities.年来,以硝态氮为核心的可持续固氮产业链被提出,融合了电催化硝态氮还原制氨、硝态氮和CO_(2)共还原制尿素等先进技术.然而,硝酸盐的生产严重依赖能源密集型过程,这需要高温和高压条件,导致大量的能源消耗和温室气体排放.因此,电催化氮氧化作为一种新型的硝酸生产途径正受到越来越多的关注.本文总结了电催化氮氧化的最新进展,重点介绍了其设计、机理和催化动力学调控.根据所讨论的结果,我们简要介绍了当前的挑战,并提出了一些未来的机遇。
