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.

Transition-metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS2), have emerged a generation of nonprecious catalysts for the hydrogen evolution reaction (HER), largely due to their theoretical adsorption energy close that platinum. However, efforts activate basal planes TMDs primarily centered around strategies introducing numerous atomic vacancies, creating vacancy–heteroatom complexes, or applying significant strain, especially acidic media. These approaches, while potentially effective, present substantial challenges in practical large-scale deployment. Here, we report gap-state engineering strategy controlled activation S atom MoS2 through metal single-atom doping, effectively tackling both efficiency and stability alkaline water seawater splitting. A versatile synthetic methodology allows fabrication series single-metal atom-doped materials (M1/MoS2), featuring widely tunable densities with each dopant replacing Mo site. Among these (Mn1, Fe1, Co1, Ni1), Co1/MoS2 demonstrates outstanding HER performance media, overpotentials at mere 159 164 mV 100 mA cm–2, Tafel slopes 41 45 dec–1, respectively, which surpasses all reported TMD-based benchmark Pt/C during splitting, can be attributed an optimal modulation associated sulfur atoms. Experimental data correlating doping density identity performance, conjunction calculations, also reveal descriptor linked near-Fermi gap state modulation, corroborated by observed increase unoccupied 3p states.
