摘　　要：通过回顾电化学氮还原(NRR)向绿色氨合成的发展过程,阐明了从传统的哈伯-博施法向新型氨合成方法转变的必要性,并对各种已被探索的催化剂进行了评估。尽管已经取得了一些进步,但电化学氮氧还原的低速率和低选择性仍然是大规模工业应用面临的挑战。通过开发氮气吸附强,还原活性高及有效抑制氢演化的催化剂,未来可能会突破这些瓶颈。In this paper,we elucidate the need for a shift from the traditional Haber-Bosch method to a novel ammonia synthesis approach by reviewing the evolution of electrochemical nitrogen reduction reaction(NRR)toward green ammonia synthesis.Various catalysts that have been explored are evaluated.Despite the advances that have been made,the low rate and low selectivity of electrochemical nitrogen-oxygen reduction remain a challenge for large-scale industrial applications.However,these bottlenecks may be broken in the future through the development of catalysts with strong nitrogen adsorption,high reduction activity,and effective inhibition of hydrogen evolution.
