Abstract Electrocatalytic water splitting driven by sustainable energy is a clean and promising water‐chemical fuel conversion technology for the production of high‐purity green hydrogen. However, sluggish kinetics anodic oxygen evolution reaction (OER) pose challenges large‐scale hydrogen production, limiting its efficiency safety. Recently, OER has been replaced nucleophilic oxidation (NOR) with biomass as substrate coupled (HER), which attracted great interest. Anode NOR offers faster kinetics, generates high‐value products, reduces consumption. By coupling reaction, can be enhanced while yielding products or degrading pollutants. Therefore, NOR‐coupled HER another new electrolytic strategy after significance realizing development global decarbonization.
