The typically the Haber‐Bosch process of nitrogen (N2) reduction to ammonia (NH3) production, expends a lot of energy, resulting in severe environmental issues. Electro‐catalytic N2 reduction to NH3 formation by renewable resources is one of the effective ways to settle the issue. However, the electro‐catalytic performances and selectivity of catalysts for electrochemical nitrogen reduction reaction (NRR) are very low. Therefore, it is of great significance to develop more efficient electro‐catalysts to satisfy the needs of practical use. Among the reported catalysts, those based on Group VIII noble metals heterogeneous catalysts display excellent NRR activities and high selectivity because of their good conductivity, rich active surface area, unfilled d‐orbitals, and the abilities with easy adsorption of reactants and stable reaction intermediates. Herein, we will introduce the progress of Group VIII precious metals heterogeneous catalysts applied in the electrocatalytic N2 reduction reaction. Then single precious metal electrocatalysts, precious metal alloy electrocatalysts, heterojunction structure electrocatalysts, and precious metal compounds based on the strategies of morphology engineering, crystal facet engineering, defect engineering, heteroatom doping, and synergetic interface engineering will be discussed. Finally, the challenges and prospects of the NH3 synthesis have been put forward. In the review, we will provide helpful direction to the development of effective electro‐catalysts for catalytic N2 reduction reaction.

基于贵金属(VIII族)的多相电催化剂用于氮还原反应的概述

通常将氮(N 2)还原为氨(NH 3)的哈伯-博世过程会消耗大量能量,从而导致严重的环境问题。将N 2电催化还原为NH 3可再生资源的形成是解决问题的有效方法之一。但是,催化剂对电化学氮还原反应(NRR)的电催化性能和选择性很低。因此,开发更有效的电催化剂以满足实际使用的需求具有重要意义。在已报道的催化剂中,基于族贵金属多相催化剂的那些催化剂具有出色的NRR活性和高选择性,因为它们具有良好的电导率,丰富的活性表面积,未填充的d-轨道,易于吸附反应物和稳定的反应中间体的能力。在此,我们将介绍应用于电催化N 2的VIII族贵金属多相催化剂的研究进展。还原反应。然后将讨论基于形态工程,晶面工程,缺陷工程,杂原子掺杂和协同界面工程的策略的单一贵金属电催化剂,贵金属合金电催化剂,异质结结构电催化剂和贵金属化合物。最后,提出了NH 3合成的挑战和前景。在本综述中,我们将为开发用于催化N 2还原反应的有效电催化剂提供有益的指导。
