Ammonia (NH3) is a vital chemical for modern human society. It is conventionally produced by the energy- and emission-intensive Haber–Bosch process. Alternatively, sustainable NH3 production from renewable electricity-driven electrolyzers has emerged as a promising route. Particularly, NH3 synthesis from nitrate (NO3−), a common pollutant in water and soil, by the nitrate reduction reaction (NO3RR) has drawn wide attention. Among various catalysts demonstrated recently, copper (Cu)-based catalysts have been recognized as attractive candidates due to their availability, good activity, high NH3 selectivity, and facile reaction kinetics. In this review, the recent progress of Cu-based NO3RR catalysts from the reaction mechanistic fundamentals to various catalyst design strategies, aiming at providing an on-time summary, is summarized, and perspectives that can guide the rational and on-demand design of Cu- and other earth-abundant metal-based catalysts for selective NO3RR toward sustainable NH3 production are elucidated.

铜基催化剂上硝酸盐电化学还原制氨的最新进展：从纳米颗粒到单原子
氨（NH 3）是现代人类社会的重要化学物质。它传统上是通过能源和排放密集型哈伯-博世工艺生产的。另外，利用可再生电力驱动的电解槽可持续生产 NH 3已成为一条有前途的途径。特别是，通过硝酸盐还原反应（NO 3 RR）从硝酸盐（NO 3 -）（水和土壤中常见的污染物）合成NH 3引起了广泛关注。在最近展示的各种催化剂中，铜（Cu）基催化剂因其可用性、良好的活性、高NH 3选择性和容易的反应动力学而被认为是有吸引力的候选者。本文综述了铜基NO 3 RR催化剂的最新进展，从反应机理基础到各种催化剂设计策略，旨在提供及时的总结和总结，并提出可指导合理和按需设计的观点。阐明了用于选择性NO 3 RR以实现可持续NH 3生产的Cu和其他地球丰富的金属基催化剂的应用。
