The electrochemical nitrogen reduction reaction (NRR), as an environmentally friendly method to convert nitrogen to ammonia at ambient temperature and pressure, has attracted the attention of numerous researchers. However, when compared with industrial production, electrochemical NRR often suffers from unsatisfactory yields and poor Faraday efficiency (FE). Recently, various structure engineering strategies have aimed to introduce extra active sites or enhance intrinsic activity to optimize the activation and hydrogenation of N₂. In this review, recent progress in atomic structure modification is summarized and discussed to design high‐efficiency NRR catalysts, with a focus on defect engineering (heteroatom doping and atom vacancy), surface orientation and amorphization, as well as heterostructure engineering. In addition, existing challenges and future development directions are proposed to obtain more credible NRR catalysts with high catalytic performance and selectivity.

原子结构修饰以电化学方式将氨还原成氨

电化学氮还原反应（NRR）作为一种在环境温度和压力下将氮转化为氨的环保方法，引起了众多研究人员的关注。但是，与工业生产相比，电化学NRR经常会产生不令人满意的产量和法拉第效率（FE）差的问题。近来，各种结构工程策略旨在引入额外的活性位点或增强内在活性以优化N ₂的活化和氢化。。在这篇综述中，总结并讨论了在设计高效NRR催化剂方面原子结构改性的最新进展，重点是缺陷工程（杂原子掺杂和原子空位），表面取向和非晶化以及异质结构工程。此外，提出了现有的挑战和未来的发展方向，以获得具有高催化性能和选择性的更可靠的NRR催化剂。
