Abstract: Electrocatalytic water splitting driven by clean energy (e.g., solar, wind) is the most promising green ways for hydrogen（H2） production. However, this process still suffers from the problem of high energy consumption. One of the main “bottlenecks” for water splitting is the sluggish four-electron OER while the generated O2 is not of significant value. Electrocatalytic organic oxidation coupled with H2 production has been proven to be an attractive approach to produce high-value-added chemicals at anode and facilitate coupled H2 production at cathode. This review provided a comprehensive summary of the recent advances in electrocatalytic organic oxidation coupled with H2 production, including the types of “active oxygen” and the reaction mechanism for catalytic organic oxidation, the strategies to enhance the reaction rate by reactants enrichment, and the design of appropriate reaction equipment. Finally,the potential prospects and challenges in this emerging electrocatalytic field were discussed ,aiming to stimulate the development of H2 production from electrocatalytic water splitting
