Here we report a nanoconfined catalytic reactor design that integrates structural confinement with localized CO2 supersaturation to enhance ethanol selectivity. Specifically, a cavity-engineered copper catalyst (CuCav-CH3@C) was developed to enrich CO2 concentrations ([CO2]) beyond their saturation limit by leveraging confined gas–liquid domains. Under these conditions, the catalyst achieves an ethanol Faradaic efficiency of 70.3% ± 3.5% and an ethanol partial current density of 245.9 ± 4.2 mA cm−2. In situ spectroscopic analysis and theoretical simulations reveal that local CO2 enrichment stabilizes the ethoxy intermediates and modulates C–O bond configurations, thereby suppressing ethylene formation and promoting ethanol selectivity. This work demonstrates how nanoconfinement and local molecular regulation can be synergistically used to tailor the microenvironment and unlock efficient pathways for producing oxygenated C2+ products. Achieving a high selectivity for multicarbon alcohols via electrocatalytic CO2 reduction on copper has proved challenging. Here a nanoconfined catalytic reactor strategy integrates localized CO2 supersaturation, leading to the stabilization of ethoxy intermediates and a 70.3% Faradaic efficiency for ethanol at practical current densities.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 9","pages":"965-975"},"PeriodicalIF":48.3,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148769326","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}

Here we show, on NiO surfaces, that in situ-generated [Ni1O1Ni4] motifs, where one Ni atom sits on an oxygen atom that bridges four surrounding Ni atoms, drive POM with promising efficiency. A Ni/Al2O3-ME catalyst with Ni loading of 0.8 wt% fabricated via deposition of preformed Ni nanoparticles onto Al2O3 achieves 92.0% CH4 conversion and 87.0% CO/H2 selectivity at 650 °C for POM, maintaining a stable H2/CO ratio of 2.0. Operando spectroscopy and environmental microscopy confirm the oxidation of metallic Ni to NiO during POM. The results of operando high-resolution annular bright-field imaging, combined with density functional theory calculations, suggest that the [Ni1O1Ni4] structure formed on the NiO(100) surface reduces the C–H activation barrier to 12.5 kcal mol−1. Thus, metallic Ni nanoparticles with high metal loadings may not be strictly required for efficient POM. The partial oxidation of methane to syngas on Ni is commonly attributed to its metallic phase. Now, by combining in situ spectroscopy and microscopy, as well as density functional theory calculations, specific Ni–O motifs are identified as the active sites on Ni/Al2O3.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 8","pages":"848-857"},"PeriodicalIF":48.3,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41929-026-01580-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its electrooxidation underpins both electrochemical hydrogen release and direct methanol fuel cells. Conventional mechanisms on Pt catalysts assume parallel indirect and direct pathways, with oxygen retained in products such as CO2 and formic acid. Here we show, using operando electrochemical-mass spectrometry with 18O-labelled water and methanol, that methanol oxidation involves previously underappreciated C–O bond cleavage. A large fraction of methanol-derived oxygen is absent from final carbon products, reaching ~65% C–O cleavage in acid and >75% in base for CO2 and CO32−, respectively, and nearly complete (>99%) cleavage for formate in base. Thus, we propose a coexisting mechanistic trajectory involving an *O*OCHOH intermediate facilitated by surface-active Pt–Ox species. Increasing pH stabilizes these sites, suppresses *CO formation and redirects selectivity towards formate. These findings provide a fundamental framework for methanol-based energy technologies. Methanol electrooxidation on Pt is believed to follow parallel indirect and direct mechanisms, involving CO* or *O*OCH intermediates, respectively. Now operando electrochemical mass spectrometry and theoretical calculations are used to propose an alternative, more prevalent mechanism in which C–O bond cleavage occurs.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"9 8","pages":"901-911"},"PeriodicalIF":48.3,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728979","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}

Here, to overcome these constraints, we report a purely organic photocatalyst that operates via a two-photon excitation mechanism, enabling both oxidative and reductive transformations within a unified platform. Upon visible-light irradiation, the molecule undergoes reversible fragmentation into three reactive subunits spanning a 5.7 V redox window. These fragments orchestrate an unusual consecutive light-induced electron-transfer mechanism that enables the orthogonal activation of thermodynamically challenging substrates. The mechanistic scenario is revealed through a combination of spectroscopic and optical techniques, supported by quantum calculations. Selectivity is mainly governed by the activity of a transiently generated catalytic species, whose presence prevents the need for external radical-sorting agents. Finally, the generality of this light-driven radical-coupling reactivity is demonstrated across a broad range of structurally diverse substrates.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"5 1","pages":""},"PeriodicalIF":37.8,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728978","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}
