Abstract Overall water splitting (OWS) to produce hydrogen has attracted large attention in recent years due its ecological‐friendliness and sustainability. However, the efficiency of OWS been forced by sluggish kinetics four‐electron oxygen evolution reaction (OER). The replacement OER alternative electrooxidation small molecules with more thermodynamically favorable potentials may fundamentally break limitation achieve production low energy consumption, which also be accompanied value‐added chemicals than or electrochemical degradation pollutants. This review critically assesses latest discoveries coupled various OWS, including alcohols, aldehydes, amides, urea, hydrazine, etc. Emphasis is placed on corresponding electrocatalyst design related mechanisms (e.g., dual hydrogenation N–N bond breaking hydrazine C═N regulation urea inhibit hazardous NCO − NO productions, etc.), along emerging reactions (electrooxidation tetrazoles, furazans, iodide, quinolines, ascorbic acid, sterol, trimethylamine, etc.). Some new decoupled electrolysis self‐powered systems are discussed detail. Finally, potential challenges prospects highlighted aid future research directions.

Electrochemical oxygen reduction reaction (ORR) is a promising alternative to the conventional anthraquinone oxidation process, with high energy consumption and massive pollutant discharge, for hydrogen peroxide (H2O2) production. However, improving selectivity of two-electron (2e–) ORR toward H2O2 remains large challenge. Here, simple scalable P, O-codoped strategy proposed improve catalytic activity low-cost carbon nanospheres (P-O-CNS). The optimal O P contents abundant defects make P-O-CNS-800 obtain highest (95.47% at 0.580 V vs RHE), greatly superior those initial O-CNS (75.74%) other P-O-CNS samples low doping content. theoretical investigation further reveals synergistic effect doped defect structures optimizing adsorption *OOH on active sites near oxygen-containing functional group as reason enhanced 2e– activity. This study offers comprehensive insight into regulating mechanism multiheteroatom improved well then provides more possibilities rational regulation catalysts high-efficiency performance.
