However, their powdery nature causes poor mechanical stability and low gas mass transfer efficiency, limiting their applications. Herein, we report a promising strategy of in situ assembly of amino-functionalized ZIF-8 (ZIF-8-NH2) on the surface of nanofibers to create the one-dimensional gas transport pathway while generating hierarchical porous architectures that increase the number of CO2-philic sites. Benefiting from the created microenvironments, the ZIF-8-NH2 fiber membranes (FMs) showed a high specific surface area of 248.29 m2/g, a high CO2 adsorption capacity of 3.25 mmol/g at 298 K and 1 bar, an excellent CO2/N2 selectivity of 37, and stable recyclability. Molecular dynamics simulations indicated that amination could enhance the CO2 affinity of ZIF-8-NH2 FMs. The gas dynamic breakthrough tests further demonstrated the high separation efficiency of the ZIF-8-NH2 FMs for the formation of CO2 and N2. The proposed collaborative regulation of microenvironments strategy provides a bright orientation for constructing functionalized MOF FMs for efficient CO2 adsorption.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"40 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epitaxial thin films offer well-defined crystallographic orientations and uniform surfaces, providing a prominent platform for the fundamental study of anisotropic and surface-driven functionalities. However, no reports have demonstrated the control of the crystallographic orientations of the metal hydroxide epitaxial thin films. In this study, using β-CoOOH as a model system, we demonstrate crystallographic orientation control of metal hydroxide epitaxial thin films using \"topotaxy\" reaction. We first fabricate the precursor β-NaxCoO2 epitaxial thin films through a reactive solid-state epitaxy using seven different single-crystal substrates: Al2O3(0001), SrTiO3(100), and (110). (111), and MgAl2O4(100), (110), (111). Subsequently, the precursor films are immsersed in an acidic solution and transformed into successfully obtain β-CoOOH (001) and (012) epitaxial thin films on the Al2O3(0001) and SrTiO3(100) substrates, respectively. Furthermore, we confirm that the surface morphology reflects the crystallographic orientations and that the coordination environment of Co ions is consistent with that of the bulk material. This study represents a significant step forward in fabricating metal hydroxide epitaxial thin films, paving the way for developing novel functionalities related to hydroxyl groups.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"86 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative analysis with literature precedents revealed a strong correlation between the luminescent behavior and the coordination environment of the Eu(III) centers.

It served as a fast transfer channel for interfacial photogenerated carriers, resulting in the formation of a direct Z-scheme heterojunction. The Z-scheme heterojunction not only maximized the redox ability but also exhibited enhanced separation and transfer efficiency of photogenerated carriers. Thereby, it exhibited excellent degradation activity and reusability for different simulated pollutants (levofloxacin, rhodamine B, and methylene blue) under LED irradiation, and its photocatalytic rate is approximately doubled. Unexpectedly, a considerable amount of H2O2 was formed via a direct one-step two-electron oxygen reduction reaction process, which played a significant role in the photodegradation process, even surpassing the role of electrons/holes as active species. Furthermore, the photodegradation pathway of levofloxacin by the Z-scheme heterojunction was analyzed.

For Tb2Te4O11, a field-induced spin-flop transition is observed below TN = 3.61 K in the isothermal magnetization M(B) curves.

Ammonium molybdate heptahydrate was used as an inner electrolyte immobilized in agar gel, while sodium sulfide with dissolved oxygen served as the outer electrolyte. We have optimized the pH levels and the oxic, hypoxic, and anoxic environments inside the reactor, which lead to local redox gradients and the competitive diffusion of oxygen and sulfide, facilitating species-specific and spatially stratified synthesis of these materials. The redox gradients exert thermodynamic control, as the diffusion coefficient of oxygen is smaller than that of sulfide. Oxic conditions resulted in the preferential formation of MoO3, even in the presence of sulfide. Conversely, hypoxic and anoxic conditions resulted in the formation of a mixture of MoO3 and MoS2 and pure MoS2, respectively. The materials were characterized for their morphological, structural, and chemical composition and speciation. The analysis revealed that MoO3 and MoS2 are both layered two-dimensional materials. We then assessed the electrocatalytic properties of the materials for the hydrogen evolution reaction (HER). It was observed that MoS2 demonstrated superior HER kinetics than MoO3.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"40 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
