H₂ production via water electrolysis is of great significance in clean energy production, which, however, suffers from the sluggish kinetics of the anodic oxygen evolution reaction (OER). Moreover, the anode product, O₂, which is of rather low value, may lead to dangerous explosions and the generation of membrane-degrading reactive oxygen species. Herein, to address these issues of electrocatalytic H₂ production, we summarize the most recent advances in three stages based on the benefit increments and various electron donation routes, which are: 1) electron donation by traditional OER: developing efficient catalysts for water oxidation to promote H₂ production; 2) electron donation by the oxidation of sacrificial agents: using sacrificial agents to assist H₂ production; 3) electron donation by electrosynthesis reaction: achieving electrosynthesis in parallel with cathodic H₂ production. Present challenges and related prospects will also be discussed, hopefully to benefit the further progress of electrocatalytic H₂ generation.

电催化制氢三部曲

通过水电解生产H ₂在清洁能源生产中具有重要意义，但其受到阳极析氧反应（OER）动力学缓慢的影响。此外，价值相当低的阳极产物O ₂可能导致危险的爆炸和膜降解活性氧物质的产生。在此，为了解决电催化H ₂生产的这些问题，我们根据收益增量和各种电子捐赠途径总结了三个阶段的最新进展，它们是：1) 传统 OER 的电子捐赠：开发高效的水氧化催化剂促进 H ₂生产; 2)牺牲剂氧化供电子：利用牺牲剂辅助H _{2 的}产生；3) 电合成反应给电子：实现电合成与阴极H ₂生产并行。还将讨论当前的挑战和相关前景，希望有助于电催化H ₂生成的进一步进展。
