Here, we present a high-valence Lewis acid incorporation strategy to enrich OH− adsorption for optimizing alkaline OER performance and for the first time demonstrate direct participation of surface hydroxyl in the alkaline OER. In particular, the optimized Sr2CoMoO6 (SCMO) with the strongest surface hydroxylation exhibits excellent alkaline OER activity and AEMWE device performance when adopted as a noble-metal-free anode electrocatalyst, achieving an industrial current density of 1 A cm−2 at a low voltage of 1.83 V and steadily operating for 100 h. Combined experimental and theoretical investigations verify that the surface hydroxyls in SCMO participate in the OER via an unusual hydrogen-bond-assisted surface hydroxyl participation mechanism. These findings offer new insights into hydroxyl electrocatalysis for AEMWE applications.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"423 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719894","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, Ru catalysts supported on anatase and rutile titanium oxide (TiO2) were evaluated for the low-temperature catalytic oxidation of representative air pollutants, including propane (C3H8), propylene (C3H6), carbon monoxide (CO), and ammonia (NH3). Rutile TiO2 significantly enhances oxidation activity over anatase TiO2 across all probe molecules. Systematic characterizations reveal that lattice matching between RuO2 and rutile TiO2 strengthens the metal-support interaction, promoting high dispersion of Ru species and stabilizing active sites. The highly dispersed Ru species on rutile TiO2 exhibit superior low-temperature redox properties, directly correlating with enhanced catalytic oxidation performance. In contrast, weaker interaction on anatase TiO2 results in lower dispersion and reduced activity. These results establish crystal-phase-dependent metal-support interactions as a key factor governing low-temperature oxidation in Ru/TiO2 catalysts and provide guidance for designing oxide-supported noble metal catalysts for air pollutant abatement.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"66 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696011","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 systematically investigated enzyme kinetics for a diverse group of cellulases and cellulosic substrates.

LFER slopes were near 1 for substrates with low crystallinity, whereas highly crystalline substrates had a slope of approximately 0.25. This provided insights into the transition state (TS) for the rate-limiting step. On crystalline substrates, the TS structure resembled the productive enzyme-substrate complex with mostly intact enzyme-substrate contacts. Conversely, for amorphous substrates, the TS was more similar to the dissociated structure with mostly broken contacts. This conclusion emphasizes the interconnected nature of substrate pretreatment and enzyme engineering, urging a holistic approach to biochemical conversion of lignocellulosic biomass.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"1 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147629859","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}

Recent work has revealed a characteristic “burst effect,” in which the first surface dehydrogenation step carries the highest barrier, while subsequent layers desorb much more easily. This perspective takes the burst effect as a unifying lens to examine how catalytic strategies reshape the initial surface step and, through it, the overall hydrogen-release behavior of MgH2. We summarize recent experimental advances in three major classes of catalysts and relate their performance to evolving atomistic mechanisms. We then discuss emerging theoretical tools, from density functional theory (DFT) calculations to machine learning interatomic potentials and descriptor-based models, that connect surface chemistry to macroscopic kinetics and enable theory-guided catalyst design. Finally, we outline key challenges and opportunities for translating burst-effect-aware design principles into practical Mg-based hydrogen storage systems.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"148 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586710","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}

Effective OOR demands catalysts that function across diverse organic substrates and a broad chemical phase space. Here, we report a well-defined Ni12P5 nanostructure as an efficient alkaline OOR catalyst for 5-hydroxymethylfurfural (HMF) and 5-amino-1H-tetrazole (AmTET), yielding carboxylated and dehydrogenative N=N-coupled products, respectively. Dynamic redox behavior and self-reconstruction were investigated to identify the active phase. At OER potentials, Ni12P5 converts into NiIII/IV oxyhydroxides typical of OER catalysts. However, upon introducing organic substrates at catalytic potentials, the in situ formed NiIII/IVOOH is rapidly reduced, generating an OOR-active material dominated by NiII sites, as evidenced by quasi in situ X-ray absorption and in situ Raman spectroscopy. This work demonstrates the versatility and robustness of Ni-based electrocatalysts formed via potential-driven material transformations.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"15 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147578132","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}
