Multicomponent alloying offers a powerful route to tune OER-active sites through inter-element electronic interactions and synergistic redox chemistry. However, the enormous compositional space makes the rational optimization of elemental ratios labor-intensive and scientifically challenging. Here, we establish a product-bubble-based high-throughput screening strategy that directly correlates oxygen bubble evolution behavior with catalytic activity, enabling rapid identification of promising compositions from a continuously varied Al–Co–Ni–Fe–Mo multicomponent alloy library. Guided by this screening, we synthesize the target composition Al<sub>32</sub>Co<sub>37.5</sub>Ni<sub>8.5</sub>Fe<sub>10</sub>Mo<sub>12</sub> on nickel foam and further activate it <em>via</em> dealloying. Dealloying induces <em>in situ</em> reconstruction into vertically aligned nanosheet arrays, selectively leaches Al, enriches Co at the surface, and promotes the formation of high-valence metal species. As a result, the dealloyed sample delivers low overpotentials of 269 mV and 312 mV at 10 and 100 mA cm<sup>−2</sup> in 1.0 M KOH, respectively, and maintains stable operation at both current densities. This work provides a fast and intuitive pathway for screening and designing non-precious multicomponent OER catalysts with promising potential for practical water electrolysis applications.</div></div>","PeriodicalId":66,"journal":{"name":"Catalysis Science & Technology","volume":"16 10","pages":"Pages 3520-3527"},"PeriodicalIF":4.0,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal oxides are promising heterogeneous catalysts for oxidative esterification, and their use in conjunction with a support phase affords synergies that can promote performance. Carbon supports are ubiquitous in catalysis due to their tuneable porosity, acid–base properties, high conductivity and chemical stability. This review discusses recent advances in the oxidative esterification of alcohols, aldehydes, alkenes, and alkynes over carbon-supported catalysts, outlining the commercial importance of esters and traditional esterification methods, and potential advantages of oxidative esterification. Methods to synthesise carbon catalysts and bifunctional heteroatom-doped analogues are introduced, with resulting structure–activity relationships for oxidative esterification highlighted, including the role of radicals.

This reveals a multi-molecular cooperative adsorption mechanism, which explains the exceptionally high adsorption strength of NO compared to predictions from single-molecule models.
