Here, we study the artificial photosynthesis of methanol in natural seawater based on a heterojunction photocatalyst (i.e. Cu2O/BMO, BMO = Bi2MoO6) and report a cation-mediated protective mechanism. Notably, it achieves an unprecedented CH3OH generation rate (501.62 μmol g-1 h-1) with high selectivity (95.8%) and long-term stability (>3 days) in natural seawater, affording abnormal performance enhancement when compared with that in pure water and surpassing the majority of reported photocatalysts to date. Theoretical calculations demonstrate that the enhanced performance in natural seawater compared to pure water arises from the strong interaction between Cu2O/BMO and cation ions that uniquely transforms the conventional ionic interference effect into a cation-mediated protective mechanism. Notably, on Cu2O/BMO surface, the cation ions (e.g., Ca2+ and Mg2+) could shield the active sites by mitigating hydroxyl (OH-) interference and stabilize the key reaction intermediates, thus enhancing both activity and stability of the overall artificial photosynthesis system.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The as-synthesized chiral hybrid films exhibit stronger circularly polarized luminescence (CPL) response than that of the corresponding 1D chiral perovskite films. The circularly polarization-resolved transient absorption (TA) spectra reveal that the enhancement of CPL response stems from the energy transfer between chiral 2D perovskite structure and the defect states of chiral 1D perovskite structure, which can increase the imbalanced spin population in the defect levels. In addition, the CPL response can be further improved by combining the chiral perovskite hybrid films with achiral silver nanowires. TA spectra demonstrate that the localized plasma field enhances the carrier recombination rate without altering their spin polarization lifetime.

Herein, we present a new metal sulfide, namely T-AMS-1, (NH4+)1.6(TU)2.3Mn0.8Sn2.2S6•0.3(H2O) (TU=thiourea), an analog of the well-known KMS-1, synthesized via a solventfree, molten thiourea flux route. Unlike KMS-type materials that host alkali metal ions, T-AMS-1 forms a hybrid organicinorganic intercalated structure in which ammonium (NH4+) cations and neutral thiourea (TU) molecules fill the interlayer space. Under optimal batch conditions, T-AMS-1 exhibits rapid kinetics (≤5 min), a high maximum removal capacity (194 mg g -1 ), and selectivity for Pb2+ ions vs. common competitive ionic species. Similarly, for Cr6+ at pH=3, the material displays rapid kinetics (≤4 min), a high removal capacity (157 mg Cr6+ g -1 ), and exceptional selectivity for Cr6+, maintaining outstanding performance even in highly complex real water and seawater matrices. Notably, T-AMS-1, as calcium alginate beads employed as the stationary phase within a column containing sea sand, demonstrates a notable ability to capture both species from real samples under continuous flow and is reusable. This work establishes a solvent-free synthetic strategy for multi-functional, layered metal sulfides that act as versatile platforms for targeted environmental decontamination.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"192 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we apply this concept to the MIL-140A(Ce) framework to systematically introduce multiple fluorinated terephthalate linkers (Fx-BDC2-), enabling precise modulation of the cooperative CO2 adsorption behaviour through the control of the framework's degree of fluorination. By simultaneously incorporating and varying the nature and content of Fx-BDC2- co-linkers (x = 1, 2, 3) while maintaining F4-BDC2- as a fixed component, we synthesised a large library of mixed-linker F4:Fx_MIL-140A(Ce) materials, whose nature of solid solutions was demonstrated. Across the series, we found that cooperative CO2 adsorption occurs above a threshold degree of fluorination of the framework of 75%, independently of fluorine positional isomerism, as demonstrated by the series of o-, m-, and pF2-BDC2- co-linkers, and is not determined by the content of the perfluorinated linker. The implication of the fluorination threshold on CO2/CH4 selectivity was also assessed, revealing that the onset of CO2-induced cooperative adsorption above this threshold is associated with a dramatic increase in selectivity towards CO2. Since the degree of fluorination of single-linker MOFs is intrinsically fixed, the mixed-linker strategy represents an effective route to continuously tune the framework's composition, thereby enabling the establishment of a structural design principle to control the emergence of cooperative CO₂ adsorption.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"293 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Doped carbon materials hold multiple advantages including tunable electronic structures, abundant polar sites, high specific surface areas, and outstanding electrocatalytic activity, which make them promising for dendrite-free sodium anodes and electrochemically stable sulfur cathodes. This review systematically deciphers the research development of doped carbon materials for Na–S batteries. The electrochemical principles and core challenges of Na–S batteries are discussed first. The key roles of doping sites in Na–S electrochemistry and various typical doping configurations are then elaborated. Next, we place emphasis on the practical applications of doped carbons in Na–S batteries, including cathode hosts, separators/interlayers, and sodium anode skeletons.

However, the fabrication of organic ferroelastics via the strategy of pH-regulated protonation remains unreported to date. Herein, we tune the protonation degree of DABCO through pH adjustment, successfully synthesizing monoprotonated DABCO-TFMS·H2O (DABCO = triethylenediamine, TFMS = trifluoromethanesulfonate) and diprotonated DABCO-(TFMS)2. The former undergoes low-temperature phase transitions without ferroelastic behaviour, while the latter exhibits a pronounced 4/mmmFmmm-type ferroelastic phase transition at 403 K, with reversible rearrangement of ferroelastic domains upon application of external mechanical stress. This work expands the ferroelastic material library, demonstrates that pH-regulated protonation is a robust strategy for achieving controllable phase transitions, and opens a new research paradigm for the development of next-generation flexible electronics and switchable devices.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"21 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents an interface-confined non-classical crystallization pathway for calcite, enabled by insoluble g-C3N4 that concurrently serves as a C/N donor, a surface-directing functional matrix, and a physical nanoscale confining scaffold. The resulting nitrogen-incorporated hybrid products exhibit a particle-attachment assembly superstructure with abundant interfacial porosity. A comparative control with soluble urea, which follows a classical ion-mediated crystallization pathway under identical hydrothermal conditions, confirms the critical role of g-C3N4 in directing particle-mediated growth. X-ray absorption near-edge spectroscopy (XANES) analyses reveal that g-C3N4-directed oriented attachment is effective in promoting heteroatom incorporation and exposing active sites, owing to the intrinsic coordination structure that enables in situ nitrogen incorporation within primary particles. Moreover, the resulting olive-shaped hybrid superstructure facilitates dopant diffusion and pore formation during subsequent decarbonation. The derived CaO exhibits a non-monotonic CO2 uptake behavior, peaking at 0.701 g-CO2/g-CaO during the second cycle while sustaining a capacity retention of 70.2% over 30 cycles. Density functional theory (DFT) analysis verified that nitrogen-induced oxygen defects can induce pronounced charge redistribution at the CO2/CaO interface and strengthen the adsorbate-surface interaction. These findings demonstrate a non-classical crystallization pathway for constructing heteroatom-modified Ca-based materials, with potential for application in calcium looping for CO2 capture.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"82 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A bifunctional S-scheme van der Waals heterojunction composed of CuInS2 and hollow porous tubular carbon nitride (CIS-TCNx) was constructed, achieving optimized band alignment and enhanced visible-light absorption. Density functional theory calculations showed that constructed S-scheme van der Waals heterojunction exhibits intense electronic interaction across the CIS-TCN boundary. In addition, the strengthened interfacial electric field (IEF) delivers sufficient driving force to guide ordered electron movement, thereby further promoting charge separation. The optimized CIS-TCN20 sample achieves a H2 production activity of 700.15 μmol g -1 h -1 in the absence of Pt cocatalyst, nearly 14-fold greater than bare CIS. With the addition of a Pt cocatalyst, H2 production rate of CIS-TCN20 could be reached 6214.14 μmol g -1 h -1 . Meanwhile, the CIS-TCN20/PMS/Vis system removes 93.3% of tetracycline (TC) and displays outstanding oxidative capability.
