Among various methods of developing hydrogen energy, electrocatalytic water splitting for hydrogen production is one of the approaches to achieve the goal of zero carbon emissions. It is of great significance to develop highly active and stable catalysts to improve the efficiency of hydrogen production. In recent years, the construction of nanoscale heterostructure electrocatalysts through interface engineering can not only overcome the shortcomings of single-component materials to effectively improve their electrocatalytic efficiency and stability but also adjust the intrinsic activity or design synergistic interfaces to improve catalytic performance. Among them, some researchers proposed to replace the slow oxygen evolution reaction at the anode with the oxidation reaction of renewable resources such as biomass to improve the catalytic efficiency of the overall water splitting. The existing reviews in the field of electrocatalysis mainly focus on the relationship between the interface structure, principle, and principle of catalytic reaction, and some articles summarize the performance and improvement schemes of transition metal electrocatalysts. Among them, few studies are focusing on Fe/Co/Ni-based heterogeneous compounds, and there are fewer summaries on the oxidation reactions of organic compounds at the anode. To this end, this paper comprehensively describes the interface design and synthesis, interface classification, and application in the field of electrocatalysis of Fe/Co/Ni-based electrocatalysts. Based on the development and application of current interface engineering strategies, the experimental results of biomass electrooxidation reaction (BEOR) replacing anode oxygen evolution reaction (OER) are discussed, and it is feasible to improve the overall electrocatalytic reaction efficiency by coupling with hydrogen evolution reaction (HER). In the end, the challenges and prospects for the application of Fe/Co/Ni-based heterogeneous compounds in water splitting are briefly discussed.
在开发氢能的各种方法中，电催化水分解制氢是实现零碳排放目标的方法之一。开发高活性和稳定的催化剂对于提高制氢效率具有重要意义。近年来，通过界面工程构建纳米级异质结构电催化剂不仅可以克服单一组分材料的缺点，有效提高其电催化效率和稳定性，还可以调节本征活性或设计协同界面以提高催化性能。其中，一些研究人员提出用可再生资源（如生物质）的氧化反应替代阳极缓慢的析氧反应，以提高整体水分解的催化效率。电催化领域现有的综述主要集中在界面结构、催化反应的原理和原理之间的关系上，一些文章总结了过渡金属电催化剂的性能和改进方案。其中，很少有研究关注 Fe/Co/Ni 基异质化合物，对阳极有机化合物氧化反应的综述也较少。为此，本文全面描述了 Fe/Co/Ni 基电催化剂的界面设计与合成、界面分类及其在电催化领域的应用。基于当前界面工程策略的发展和应用，讨论了生物质电氧化反应（BEOR）替代阳极析氧反应（OER）的实验结果，并通过与析氢反应（HER）耦合，提高整体电催化反应效率是可行的。最后，简要讨论了 Fe/Co/Ni 基异质化合物在水分解中的应用所面临的挑战和前景。
