摘要 基于绿色电能电解水制氢对于实现碳中和具有重要意义,然而电解水制氢需要较高的过电位驱动动力学缓慢的阳极析氧反应(OER),这显著限制了电解效率。通过采用热力学上更优的有机小分子氧化反应替代传统析氧反应,不仅能有效降低能耗和提升能效,还可通过高附加值小分子化学品的生成,显著提升该反应路线的技术经济性,从而拓宽了绿氢制取技术的市场应用前景。重点介绍了广受关注的醇类小分子电催化氧化反应体系及其反应机制,系统性地归纳总结了适用于醇类小分子电解制氢体系的高性能阳极催化材料体系研究进展,探讨了醇类小分子电催化氧化反应中尚存的挑战并展望了该领域未来的可能发展方向。旨在为阳极小分子替代OER技术方案的商业化应用提供一定的借鉴。

Abstract: The electrolysis of water for hydrogen production based on green electricity is of great significance for achieving carbon neutrality. However, the sluggish kinetics of the oxygen evolution reaction (OER) at the anode, which requires a high overpotential, significantly limits the efficiency of water electrolysis for hydrogen production. In the field of green hydrogen production, traditional water electrolysis technologies face challenges such as slow kinetics of the anodic oxidation reaction and high production costs, severely limiting their commercialization. By using organic small molecule oxidation reactions with better thermodynamic and kinetic performance to replace traditional OER, energy consumption can be effectively reduced and energy efficiency improved, meanwhile the generation of value-added small molecule chemicals can also significantly enhance the technical and economic feasibility of this reaction pathway, thereby broadening the market application prospects of green hydrogen production technologies. This review focuses on the widely studied systems of electrocatalytic oxidation reactions of small molecule alcohols and their reaction mechanisms. We systematically summarize the research progress of high-performance anode catalytic materials systems applicable to alcohol small molecule electrolysis for hydrogen production. We also present the remaining challenges in electrocatalytic oxidation reactions of alcohols and prospects for future development directions in this field. The aim is to provide some guidance for the commercial application of anodic oxidation of small organic molecules for replacing OER.
