However, the implementation of such catalytic systems remains challenging due to inherent incompatibilities between chemical and enzymatic processes. To address that, we developed a biocompatible approach that combines polymeric micelles with living cells to achieve a recyclable photoenzymatic cascade. In this process, the charged micelles encapsulating photocatalysts are attached to the surface of benzaldehyde lyase-expressing Escherichia coli (E. coli) cells. Notably, the coated E. coli cells not only retained their intrinsic enzymatic activity but also enabled an efficient one-pot photoenzymatic cascade. Furthermore, the micelle-coated cells retained over 83% of their original activity after five catalytic cycles. Consequently, our approach offers a polymeric micellar platform for achieving a recyclable photoenzymatic cascade, with the potential to be extended to other chemoenzymatic cascades, thereby providing a promising strategy for efficient industrial synthesis.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"17 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183392","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}

The electronic metal-support interaction determines not only the local coordination environment in shaping the stability and reactivity of Pt on support, but also the covalency of Pt–O and electron transfer properties. Here, we reveal the impact of different anchoring mechanisms between Pt ASL and supports on catalytic activity and product selectivity of NH3 oxidation. The Pt ASL consumes more low-coordination terminal hydroxyls on Al2O3, and the lower coordination number leads to the stronger electron transfer between Pt ASL and TiO2. The imino group acts as the key intermediate on Pt/TiO2 resulting in higher NH3 conversion but lower N2 selectivity, whereas the amino group plays a dominant role on Pt/Al2O3 leading to slightly lower NH3 conversion but higher N2 selectivity because of rapid NH3∗ dehydrogenation.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"19 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116727","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 overcome this by integrating sulfur/oxygen dual-polarity units into electron-deficient naphthalene diimide (NDI)-based donor-acceptor (D-A) π-frameworks, achieving spatiotemporal electron-hole decoupling. Experimental and theoretical analyses indicate that this dual-polarity architecture gives rise to tandem endogenous electric fields and robust macroscopic polarization, creating spatially separated “electron platforms” and “hole superchannels,” which reduce recombination and accelerate redox kinetics. Crucially, polarization-induced ordered molecular alignment aligns reactant orientations and lowers N≡N dissociation barriers, enabling concurrent oxygen reduction and nitrogen oxidation. The optimized catalyst achieves a record nitrate yield of 8.89 mg g−1 h−1 with an apparent quantum efficiency of 5.50%, outperforming state-of-the-art metal-free systems. Our work introduces innovative design principles and offers a profound perspective for achieving differential bidirectional control over electron and hole carrier transfer rates.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"190 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116674","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}

Nevertheless, catalytic asymmetric methods for synthesizing chiral spiroketals remain scarce. Here, we report an asymmetric catalytic halogenation of racemic olefinic hemiketals to synthesize chiral halo-spiroketals. The approach utilizes a cross-assembled bifunctional catalyst system that integrates a chiral phosphoric acid with an achiral quinoline base. Optimization of the reaction was accomplished mainly by modifying the cost-effective achiral quinoline. The reaction mechanism is characterized by a dynamic kinetic resolution of hemiketal and a diastereoselective bromocyclization, underscoring the critical function of the achiral quinoline base throughout both phases of the catalytic process. The chiral halo-spiroketals are important intermediates for the synthesis of chiral spiroketal phosphine ligands, which can be applied in various asymmetric catalytic reactions. The halogen substituents in the spiroketal phosphine ligands enable late-stage modifications that aid in the selection of suitable ligands for particular reactions.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"46 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145068131","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}
