As an oxide support, porous single-crystal zirconia monoliths would combine the advantages of activity similar to nanocrystals and stability similar to bulk crystals. In this work, we fabricated a porous single-crystal zirconia monolith and deposited single-crystal NixFe1-x alloy nanoparticles to form well-defined metal-oxide interfaces for the control of metal-oxide interactions to enhance catalytic performance and durability. As a case study, we showed outstanding performance with conversion efficiencies of CH4 and CO2 reaching ∼88.9% and 91.7% for dry reforming of CH4/CO2, respectively, without visible performance degradation even during continuous operation for 240 h at a low temperature of ∼650°C. The current work opens a new avenue for developing high-efficiency catalysts for carbon reclamation at low temperatures, and the present techniques can create well-defined active interface structures for catalyst designs.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"65 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147360090","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}

We introduce an asymmetric donor strategy coupling diazine donors with an o-phthalaldehyde acceptor to strengthen push-pull interactions for enhanced π-conjugated charge transfer. The optimized polymers, PaTapm and PaDamp, achieve H2O2 yields of 829.67 and 1,649.12 μmol·g−1·h−1, with solar-to-chemical efficiencies of 0.238% and 0.395%, respectively. Computations show that disulfide-functionalized diazine frameworks facilitate electron excitation/transport, O2 adsorption, and ∗OOH/∗H2O2 formation. Mechanism studies support 2e− oxygen reduction reaction and 4e− water oxidation reaction pathways of polymers for continuous H2O2 production. However, partial polymer self-oxidation by holes is also observed, slightly affecting long-term photostability without sacrificial agents. Prototype reactors enable large-scale H2O2 production under natural sunlight, and PaDamp-mediated photocatalytic-Fenton treatments highlight potential for water remediation. This work offers atomic-level insights into the role of asymmetric donor engineering in catalytic optimization.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"411 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147329955","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}

Despite the significant advances, the established β-fluorinated alkyl radical precursors generally suffer from limitations in their molecular complexity and diversity. In this study, 1,3-benzodithiolylium tetrafluoroborate is identified as an efficient hydroxyl-activating reagent to enable the direct utilization of readily available and structurally diverse β-fluorinated alcohols as versatile synthetic building blocks for fluoroalkylation. The unique radical deoxygenation process is mediated by site-selective hydrogen atom transfer with a photoexcited triplet ketone/nitroarene, providing efficient access to high-energy β-fluorinated primary alkyl radicals. The efficiency and universality of this deoxygenative fluoroalkylation strategy have been demonstrated by the achievement of a series of unprecedented photocatalytic fluoroalkylation reactions with β-fluorinated alcohols, including anthraquinone/cobaloxime dual-catalyzed dehydrogenative fluoroalkylation of alkenes/alkanes with hydrogen evolution and triplet nitroarene-mediated oxo-fluoroalkylation of alkenes under metal-free conditions.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"291 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147319897","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}

However, the effects of spatial confinement and the role of cerium (Ce) species remain poorly understood. Here, we reveal that Ce-incorporated dealuminated beta zeolite (CedeAlBEA) exhibits exceptional isobutene selectivity when Ce species are atomically dispersed within the BEA framework. Spectroscopy analyses show that isolated Ce atoms provide optimal Lewis acidity for facilitating selective isobutene formation. In contrast, increasing Ce loading leads to the formation of CeO2 nanoparticles, promoting mesityl oxide (MSO) as a byproduct. The Ce species in CedeAlBEA enhance C–C coupling and deoxygenation selectivity, whereas mesoporous and non-porous supports favor MSO formation because of the weaker confinement effects. Kinetic experiments reveal that oxygen elimination is the rate-limiting step. This study highlights the critical role of confined, atomically dispersed Ce cations in the BEA framework in directing acetone throughout diacetone alcohol decomposition to isobutene.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"13 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147279749","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}
