Abstract

The electrocatalytic reduction of nitrate to ammonia (NRA) technology not only achieves the effective removal of nitrates in the environment but also produces value-added products-NH₃. In recent years, copper-based materials have shown tremendous application prospects in this field due to their excellent conductivity, moderate cost, and their proximity of d orbital energy levels to the LUMO π∗ molecular orbitals of nitrate. This review starts with copper-based catalysts to elucidate the reaction mechanisms of NRA and its influencing factors, while summarizing and analyzing the principles and pros and cons of various modification strategies. Then, we will explore the impact of different modification strategies on improving NRA performance and the underlying theoretical mechanisms. Finally, this review proposes the current challenges and prospects of copper-based materials, aiming to provide a reference for the further development and industrial application of copper-based catalysts.

精确调节铜基电催化剂的结构，实现硝酸盐可持续还原成氨。

电催化硝酸盐还原成氨（NRA）技术不仅能有效去除环境中的硝酸盐，还能产生高附加值产品--NH3。近年来，铜基材料以其优异的导电性、适中的成本以及与硝酸盐 LUMO π* 分子轨道接近的 d 轨道能级，在这一领域展现出巨大的应用前景。本综述将从铜基催化剂入手，阐明硝酸纤维素的反应机理及其影响因素，同时总结和分析各种改性策略的原理和利弊。然后，我们将探讨不同改性策略对提高 NRA 性能的影响及其背后的理论机制。最后，本综述提出了铜基材料当前面临的挑战和发展前景，旨在为铜基催化剂的进一步发展和工业应用提供参考。
