Research Progress of Electrocatalytic Nitrogen Reduction for Ammonia Synthesis

在温和条件下用氮气(N_(2))合成氨(NH_(3))是化学领域最有吸引力的课题之一。电催化还原N_(2)有望利用可再生能源实现清洁和可持续的氨生产。到目前为止,在室温和大气压下将N_(2)电催化还原为氨的新兴电催化剂得到了广泛的探索。同时实现高催化活性和高选择性合成氨是主要挑战。本文从理论和实验两方面叙述了在室温和常压下电催化氮还原反应(NRR)合成氨的研究进展。

Nitrogen(N_(2)) to ammonia(NH_(3)) under mild conditions is one of the most attractive topics in the chemical field.Electrochemical reduction of N_(2) is expected to use renewable energy to achieve clean and sustainable ammonia production.To date,emerging electrocatalysts for the electrochemical reduction of N_(2) to NH_(3) at room temperature and atmospheric pressure has been widely explored.Achieving high catalytic activity and high selectivity of ammonia synthesis is the main challenge.In this paper,the progress of electrochemical nitrogen reduction reaction(NRR)at room temperature and atmospheric pressure is reviewed theoretically and experimentally.
