Abstract

Electrochemical urea oxidation reaction (UOR) is a promising alternative to oxygen evolution reaction (OER) for realizing energy-saving hydrogen production. Developing efficient electrocatalysts for UOR becomes a central challenge. Recently, amorphous materials have been extensively used as UOR catalysts because of their numerous defective sites and flexible electronic properties. In this review, recent advancements in the development of amorphous UOR electrocatalysts are analyzed. The UOR mechanism is discussed, and the design of amorphous catalysts is then analyzed. The main catalyst design strategies are illustrated, including nanostructure control, heteroatom doping, composition regulation, and heterostructure construction. Also, electrocatalysts’ structure-performance correlation is interpreted. Perspectives in this field are proposed for guiding future studies on the development of high-performance amorphous catalysts towards energy sustainability.

用于尿素氧化反应的非晶态电催化剂

电化学尿素氧化反应（UOR）是氧进化反应（OER）的一种很有前途的替代反应，可实现节能制氢。开发用于尿素氧化反应的高效电催化剂成为一项核心挑战。近来，非晶材料因其具有众多缺陷位点和灵活的电子特性而被广泛用作 UOR 催化剂。本综述分析了非晶 UOR 电催化剂开发的最新进展。首先讨论了 UOR 的机理，然后分析了非晶态催化剂的设计。文章阐述了催化剂的主要设计策略，包括纳米结构控制、杂原子掺杂、成分调节和异质结构构建。此外，还解释了电催化剂的结构-性能相关性。提出了该领域的前景展望，以指导未来开发高性能非晶催化剂的研究，实现能源的可持续发展。
