Ammonia is an important chemical raw material, widely used in industry and agriculture, as well as an important energy storage intermediate and carbon‐free energy carrier. But, its production is limited to the traditional Haber‐Bosch process. Recently, electrochemical reduction of N₂ has been attracting more and more attention, owing to the lower energy consumption and because it is environmentally friendly. However, there are a lot of problems that remain to be solved, and the main challenges are the low selectivity and catalytic activity when using this process. In this Review, we first summarize the recent development of electrocatalysts for electrochemical N₂ reduction and elaborate on the reaction mechanisms of the nitrogen reduction reaction (NRR). In addition, the effects of different types of electrolyte on the NRR activity and electrolyte choice are discussed. Finally, the perspectives of electrochemical nitrogen reduction for conversion to ammonia are discussed.

常压条件下氮还原电化学合成氨的新进展

氨是重要的化学原料，广泛用于工业和农业，也是重要的储能中间体和无碳能量载体。但是，其生产仅限于传统的Haber-Bosch工艺。近来，由于较低的能量消耗并且因为它是环境友好的，所以N _2的电化学还原已经引起越来越多的关注。但是，仍有许多问题有待解决，主要挑战是使用该方法时选择性低和催化活性低。在这篇综述中，我们首先总结了电化学催化剂N ₂的最新进展。还原并详细说明了氮还原反应（NRR）的反应机理。此外，还讨论了不同类型的电解质对NRR活性和电解质选择的影响。最后，讨论了将电化学氮还原为氨的方法。
