H 2 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, O 2 , 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 H 2 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 H 2 production; 2) electron donation by the oxidation of sacrificial agents: using sacrificial agents to assist H 2 production; 3) electron donation by electrosynthesis reaction: achieving electrosynthesis in parallel with cathodic H 2 production. Present challenges and related prospects will also be discussed, hopefully to benefit the further progress of electrocatalytic H 2 generation.
