Here we report that controlling the formation of subnanometre PtSn alloyed clusters encapsulated in silicalite-1 affords a catalyst that can sustain high propylene productivities. At 165 h−1, the catalyst achieved about 1 molC3H6 gcatalyst−1 h−1 for more than 300 hours, with >99% propylene selectivity. Furthermore, the spent catalyst can be effectively regenerated using simple air calcination. Detailed characterization and computational modelling attribute the high PDH performance to the distinctive electronic structures of the Pt sites within subnanometre alloyed clusters. The dynamic structures of these subnanometre alloyed clusters probably allow these Pt sites to access a broader range of electronic and structural configurations, expanding the reaction’s accessible energy landscape and effectively breaking the longstanding trade-off between productivity and stability that constrains conventional PDH catalysts. PtSn catalysts are most effective for propane dehydrogenation but structural tunability remains challenging. Now the use of molecular complex precursors unlocks access to subnanometre alloyed PtSn clusters within silicalite-1. The Pt in the clusters undergoes diverse and rapid interconversion among different electronic structures, resulting in high performance and stability.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 5","pages":"552-564"},"PeriodicalIF":44.6,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148040011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, practical realization of this potential is limited by the lack of a generic method to incorporate multiple types of non-metal into single-phase CCAs. Here we present a facile solvothermal strategy enabling the incorporation of fluorine, boron and nitrogen into the interstitial sites of Pt-based CCAs. Mechanistic investigations unravel three decisive factors for the synthesis: prior formation of Pt clusters catalysing 3d-transition-metal reduction, coordination and activation of non-metal precursors by 3d-transition-metal ions, and rational selection of non-metal-containing functional groups. This methodology yields a library of non-metal-hybridized interstitial CCAs with tuneable compositions. Notably, selected Pt-based CCAs demonstrate exceptional performance as oxygen reduction electrocatalysts for fuel cells, with outstanding activity and durability surpassing state-of-the-art benchmarks. These non-metal-hybridized interstitial CCAs offer a promising platform for tackling demanding electrocatalytic processes involving complex tandem reaction steps. Pt-based alloys are among the most active catalysts for fuel cells, but strategies to improve their performance are still needed. Now a series of non-metal-modified Pt-based compositionally complex alloys is prepared via a general solvothermal approach and tested for the oxygen reduction reaction, where PtCuNiCoN is shown to exhibit excellent performance.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 6","pages":"584-597"},"PeriodicalIF":48.3,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Direct aqueous electrooxidation is a safe and sustainable alternative that uses water as an oxygen source at a catalytically competent anode. Until now, the direct aqueous route has only been demonstrated on noble metals (Pd, Pt, Au, Ag), which are unstable unless operated in halogenated electrolytes. Here we have developed a noble metal- and halogen-free catalytic system using a cobalt-based perovskite oxide with a Faradaic efficiency of 40% toward propylene oxide and propylene glycol, maintained over 24 h of operation. Kinetic analysis revealed potential-dependent rate-limiting steps involving electrochemical oxygen species generation and thermochemical oxygen transfer to propylene. This work establishes a cost-effective and safe synthetic route with earth-abundant non-noble metal-based catalysts, not only for propylene epoxidation but also for other heterogeneous oxygen-transfer reactions. Direct electrocatalytic oxidation of propylene in aqueous solution has been limited to precious-metal catalysts in halogenated electrolytes. Now, a perovskite oxide has achieved 40% Faradaic efficiency towards propylene oxide and glycol using water as the oxygen source in a phosphate/polyphosphate electrolyte.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 5","pages":"542-551"},"PeriodicalIF":44.6,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148040019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, precisely controlling the compositions of supported bimetallic or multi-metallic clusters and maintaining their stability under high-temperature reaction conditions presents a substantial challenge. Here we show that the migration of K and Sn species during ethane dehydrogenation over multiple reaction–regeneration cycles aggravates the compositional heterogeneity of K–Pt–Sn clusters encapsulated within MFI zeolite, thereby promoting coke formation and accelerating catalyst deactivation. Through a water-soaking treatment, we achieve the redistribution of K and Sn species within the MFI zeolite, thereby constructing sub-nanometre K–Pt–Sn active sites with optimal composition. The resulting catalyst delivers high ethylene yields, ethylene selectivity above 99%, and a stable lifetime of over 3,600 h over multiple reaction–regeneration cycles. Pt-based alloy clusters within zeolite channels are promising catalysts for the dehydrogenation of alkanes, but controlling their distribution under operation is challenging. Now a water-soaking treatment to regenerate and minimize atom migration in K–PtSn@MFI catalysts is introduced, resulting in enhanced stability for non-oxidative ethane dehydrogenation.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 5","pages":"516-529"},"PeriodicalIF":44.6,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148040010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By coupling photoredox catalysis and metalloenzyme catalysis, here we harness cooperative photometallobiocatalysis to merge enzymatically generated, open-shell iron carbenoids with reactive radical intermediates formed via excited-state chemistry. This strategy expands the scope of intermolecular radical C–C coupling reactions with excellent enantio- and diastereoselectivities. Central to the successful implementation of this design is the directed evolution of a small metalloprotein catalyst, derived from a thermophilic cytochrome c, to achieve challenging stereocontrol in radical C–C coupling via an outer-sphere mechanism. These photobiocatalytic, formal metal carbenoid–radical coupling reactions advance a distinct mode of stereoselective outer-sphere metal carbenoid chemistry, providing a powerful strategy to design and evolve biocatalytic C–C bond-forming reactions through otherwise challenging intermolecular asymmetric radical couplings. Stereoselective radical C–C couplings remain a major challenge.

Here we leverage a multimodal optical imaging platform to probe the charge-transfer efficiency between Shewanella oneidensis MR-1 and {110}/{001}-faceted haematite, at single-particle and single-cell levels, in vivo and operando. We quantify the reverse extracellular electron-transfer capabilities of Shewanella oneidensis MR-1 via non-H2-mediated pathways, and identify that haematite’s {110} facets synergistically exhibit stronger cell-binding ability and higher charge-transfer efficiency. Furthermore, we discover that moderate cell densities are key to enhancing per-cell electron injection, highlighting the trade-off between total loading and individual cell efficiency, and offering critical insights into biofilm structure optimization. Our imaging tools and analytical framework may potentially extend to diverse microbe–semiconductor hybrid systems, quantifying microscopic structural and functional descriptors that enhance the fundamental understanding of complex interfacial charge transfer, and inform rational biohybrid design across applications. Understanding the charge transfer at microbe–semiconductor interfaces in biohybrids is valuable for advancing solar-to-chemical conversion.
