Electrocatalytic urea synthesis from CO and nitrogenous substances represents an essential advance for the chemical industry, enabling the efficient utilization of resources and promoting sustainable development. However, the development of electrocatalytic urea synthesis has been severely limited by weak chemisorption, poor activation and difficulties in C-N coupling reactions. In this review, catalysts and corresponding reaction mechanisms in the emerging fields of bimetallic catalysts, MXenes, frustrated Lewis acid-base pairs and heterostructures are summarized in terms of the two central mechanisms of molecule-catalyst interactions as well as chemical bond cleavage and directional coupling, which provide new perspectives for improving the efficiency of electrocatalytic synthesis of urea. This review provides valuable insights to elucidate potential electrocatalytic mechanisms.
由一氧化碳和含氮物质进行电催化尿素合成是化学工业的一项重要进展，能够实现资源的高效利用并促进可持续发展。然而，电催化尿素合成的发展受到化学吸附较弱、活化不足以及C-N偶联反应困难等因素的严重限制。在这篇综述中，从分子-催化剂相互作用以及化学键断裂和定向偶联这两个核心机制的角度，总结了双金属催化剂、MXenes、受阻路易斯酸碱对和异质结构等新兴领域中的催化剂及相应反应机制，为提高电催化尿素合成效率提供了新的视角。这篇综述为阐明潜在的电催化机制提供了有价值的见解。
