The electrochemical oxidation of small molecules to generate value-added products has gained enormous interest in recent years because of the advantages of benign operation conditions, high conversion efficiency and selectivity, the absence of external oxidizing agents, and eco-friendliness. Coupling the electrochemical oxidation of small molecules to replace oxygen evolution reaction (OER) at the anode and the hydrogen evolution reaction (HER) at the cathode in an electrolyzer would simultaneously realize the generation of high-value chemicals or pollutant degradation and the highly efficient production of hydrogen. This Minireview presents an introduction on small-molecule choice and design strategies of electrocatalysts as well as recent breakthroughs achieved in the highly efficient production of hydrogen. Finally, challenges and future orientations are highlighted.
近年来，小分子的电化学氧化因其操作条件温和、转化率和选择性高、无需外加氧化剂以及环境友好等优点而受到极大关注。在电解池中，将小分子的电化学氧化与阳极析氧反应（OER）和阴极析氢反应（HER）耦合，可以同时实现高附加值化学品的生成或污染物的降解以及氢气的高效生产。本综述介绍了小分子的选择和电催化剂的设计策略，并介绍了高效制氢方面的最新突破。最后，强调了面临的挑战和未来的发展方向。
