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.

Abstract Developing electrooxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) in a weak alkaline medium can potentially inhibit HMF degradation humins and thus mitigate carbon loss that is encountered strong media; however, the activity often compromised under low OH − concentration. Herein, by incorporating chromium oxide (CrO x ) as hard Lewis onto CoO surface (CoO –CrO ), largely boosted 1 m carbonate buffer (pH 11), including higher FDCA Faradaic efficiency (from 41% 90%), selectivity 33% 92%), yield 28% 89%). The electrolysis tolerate high initial concentration (100 showing balance (97%) compared with alkali (≈70%). Experimental data reveal CrO accelerates migration from bulk electrode enriches at electrode–electrolyte interface, enhancing catalyst reconstruction reaction intermediate conversion, promoting activity. Furthermore, interfacial enrichment strategy demonstrated effective for other biomass‐derived molecule (ethylene glycol glycerol) electrooxidations. This work demonstrates hard‐Lewis‐acid‐induced dynamically optimizes microenvironment, establishing new design principle efficient electrocatalytic systems conditions.
