Herein, we introduce a “self-sustaining alkaline local microenvironment” strategy enabled by a MnFe dual-site oxide that concurrently serves as a structural scaffold and catalytic mediator, in which inactive FeOh sites in FeOx are selectively substituted by Mn while active FeTd sites are retained. Fe sites in 1D MnFeOx activate NO3− and dynamically capture OH− to form FeOOH, establishing a localized alkaline microenvironment around the active sites at electrode—electrolyte interface that effectively suppresses HER. Concurrently, Mn sites stabilize the high-valent Fe species and continuously split interfacial H2O into OH− and H*, ensuring the robust persistence of the alkaline microenvironment. The resulting 1D MnFeOx catalyst delivers an NH3 Faradaic efficiency of 95.9% (12.3 mg h−1 cm−2) in neutral media and operates stably for over 20 h without degradation. By advancing local pH regulation from external intervention to intelligent self-regulation, this work offers a new insight in adaptive electrocatalyst design and regulating the interfacial microenvironment beyond NO3RR.\u0000 </div>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147708017","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 being discovered over 40 years ago, TS-1 is seeing an increase in use in the chemical industry. The catalyst structure, especially the Ti speciation and local environment in the zeolitic framework, as well as the nuclearity of the Ti sites in the pristine zeolite material, are still debated. Here, we address this issue by applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS-1 catalysts. For extra-framework-free TS-1 catalysts, the Ti sites are associated with a distinct NMR signature—δiso (49Ti) = −900 ppm; CQ,0(49Ti) = 7.2 MHz—which can be translated into structural parameters and a dominant first coordination environment according to an extended Czjzek model. With the implementation of a 47/49Ti NMR crystallography protocol, benchmarked on molecular models, this signature was assigned to the presence of mononuclear Ti framework sites in pristine TS-1 structures. The observed distribution of the NMR parameters presumably originates from variations of mononuclear Ti framework sites in the first and second coordination sphere, likely due to the occupancy of several T-sites.","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ange.202524232","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147708277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Benefiting from these attributes and the intrinsic ferroelectric spontaneous polarization, the X-ray detector based on (HDA)Sb0.39Bi0.61I5 exhibits excellent self-powered detection performance with a high sensitivity of 1,040 µC Gyair−1 cm−2 and a low detection limit of 0.25 nGyair s−1.

Mimicking this intricate design in artificial materials has remained elusive, as achieving simultaneous, precisely control over both pore architecture and chemical composition hierarchies within a single system posed great challenges. In this work, by developing a facile nanoemulsion-based post-synthetic strategy, we break this barrier and achieve multivariate hierarchies in metal–organic frameworks (MOF) single crystal, enabling the first creation of MOF with simultaneously sequentially ordered hierarchical pores (micropores→mesopores→macropores) and hierarchical chemical compositions (distinct functional layers). This true biomimicry showcase promoted charge transfer efficiency and accelerated reaction kinetics which are similar to the natural systems. In addition, novel multivariate hierarchies like “multi-element hierarchical pores” for multifunctionality and “cross-linked hierarchical pores” for pore structural hybridization can be also created, transcending traditional material limits.
