Here, we report a multimetallic Hofmann MOF in which chromium directs surface reconstruction while preserving the crystalline framework. Operando spectroscopy and theoretical calculations show that Cr–N interactions promote preferential reconstruction at Fe–N sites, modify the electronic structure, and lower the barrier for active-phase formation. The reconstructed oxyhydroxide exhibits a higher d-band center and Fermi level, leading to faster OER kinetics. As a result, the catalyst delivers an overpotential of 243 mV at 10 mA cm−2 and maintains stable operation for 180 h. In an anion-exchange membrane water electrolyzer, it achieves a current density of 3.375 A cm−2 at 2.0 V. This work demonstrates a strategy for controlling MOF reconstruction through electronic-structure engineering and provides design principles for durable OER catalysts and practical water electrolysis.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"36 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report a reaction-driven exsolution strategy in multi-metallic spinel ferrites that enables the in situ formation of active nanocomposite phases during CO2 hydrogenation and thus eliminates the need for any pre-treatments. We also demonstrate that depending on the exsolution environment, we can produce single metal and/or ternary nanoparticles. Operando spectroscopy reveals a bifunctional tandem mechanism in which Cu and Ni sites catalyze CO2 activation, while the iron carbide phases, dynamically forming under reaction conditions, promote C–C coupling and hydrocarbon chain growth. This reaction-induced restructuring leads to enhanced activity and selectivity toward short-chain hydrocarbons. These findings identify reaction-driven exsolution as a strategy for controlling active phase formation under working conditions, and they define a direct relationship between exsolution dynamics and catalytic performance and provide new insight into the design of energy-efficient, adaptive catalysts.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"149 1","pages":"101896"},"PeriodicalIF":9.4,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149092495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we modulate the electronic environment of surface Rh through Fe incorporation and develop supported Rh-Fe intermetallic nanoparticles (Rh1Fe1) for 1-octene hydroformylation. Rh1Fe1 delivers a turnover frequency of 22,288 h−1, 1.78-fold higher than that of monometallic Rh and one that exceeds previously reported heterogeneous Rh systems and the benchmark Wilkinson catalyst. Combined characterization and density functional theory (DFT) calculations reveal that moderate Fe incorporation downshifts the Rh d-band center, weakens Rh–CO binding, and lowers reaction barriers, thereby accelerating hydroformylation. In contrast, excessive Fe further downshifts the Rh d-band center and weakens H2/olefin adsorption, suppressing catalytic activity. Accordingly, the intrinsic activity of Rh1Fex follows a volcano-type dependence on Fe content. These findings rationalize the optimal performance of Rh1Fe1 and provide guidance for designing Rh-based hydroformylation catalysts and other bimetallic intermetallic materials.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"21 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
