As a typical metal-free semiconductor, graphitic carbon nitride (g-C3N4, also known as CN) has attracted widespread research interest owing to its ability to absorb visible light and adjustable electronic properties. Nevertheless, fast recombination of photogenerated carriers and low light utilization still limit its large-scale practical use. Thus, a synergistic B/Cu nanocomposite-modified carbon nitride (CN–B–Cu@C) is rationally designed and synthesized to efficiently produce H2via photocatalytic water splitting. Boron doping generates defect sites on CN, while copper modification creates electron-enriched active sites on the catalyst surface. The dual-modification strategy effectively strengthens the surface-built-in electric field of the carbon nitride matrix. Driven by the prominent synergistic interaction between B and Cu active components, the optimized CN–B–Cu@C 1% composite delivers a competitive photocatalytic H2 generation rate of 1499.33 μmol h−1 g−1 under visible light irradiation (λ ≥ 420 nm) with sacrificial agents. Such a hydrogen production activity is approximately 6.1-fold higher than that of pristine CN (245.67 μmol h−1 g−1), and the corresponding apparent quantum yield (AQY) reaches 5.02% at 450 nm. Furthermore, the synthesized composite also possesses outstanding cycling durability, with no obvious activity attenuation observed after a continuous 20-hour photocatalytic reaction test. This work provides a feasible strategy for constructing synergistic metal/nonmetal co-modified carbon nitride photocatalysts, offering a promising pathway for developing high-performance photocatalytic systems toward clean hydrogen generation.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"9 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225897","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}

Here, we propose a room-temperature spontaneous chemical reconstruction strategy grounded in the hard–soft acid–base theory, achieving a phase transition from V2O5 to oxygen-deficient KV3O8via a facile coprecipitation method. We reveal that the strong interaction between K+, acting as a mild Lewis acid, and lattice oxygen not only enables K+ intercalation to construct structural pillars but also thermodynamically induces spontaneous lattice oxygen loss, thereby introducing oxygen vacancies and establishing a V4+/V5+ mixed-valence system. This dual effect simultaneously enhances intrinsic electronic conductivity, widens interlayer ion-transport channels, and lowers diffusion barriers, yielding ultrafast Zn2+ diffusion kinetics with a diffusion coefficient of 1.3 × 10−10 cm2 s−1. Consequently, the KV3O8 cathode delivers a high specific capacity of 342.4 mAh g−1 at 0.3 A g−1 and retains 81.1% capacity after 5830 cycles at 5 A g−1. Moreover, a flexible pouch cell assembled with this cathode exhibits exceptional voltage stability and capacity retention under severe mechanical bending.

Their adsorption behavior on Au(111) is investigated by combining scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). All compounds exhibit a general tendency to adsorb on Au(111). However, the resulting surface organization is found to depend strongly on the molecular structure of the organic-inorganic hybrids, adsorption conditions, and solvent. As a consequence, a wide range of nanoscale architectures is obtained, including single molecules, sparse aggregates, compact monolayers, multilayers, and larger molecular agglomerates. Scanning tunneling spectroscopy (STS) measurements reveals the characteristic four-step resistive switching behavior of V6-based molecules immobilized on the surface. Notably, the optimized V6/Au(111) interface exhibits exceptional stability of the immobilized molecules, enabling both forward and backward potential sweeps to be recorded within a single roomtemperature STS experiment. These measurements provide the first direct experimental evidence of fully reversible, four-step switching of a V6-oxo core strongly coupled to a conductive metal surface.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"12 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218197","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}

Through electrostatic self-assembly with CuCo-PBA, a novel S-scheme het-erojunction photocatalyst (ZnS-Vs/CuCo-PBA) was constructed for photocatalytic hy-drogen production and peroxymonosulfate (PMS) activation to degrade polystyrene (PS) microplastics. Morphological and structural characterization indicates that ZnS inherits the regular morphology of ZIF-8, exhibits tight interfacial bonding with CuCo-PBA, and uniform elemental distribution. Band structure and photoelectrochemical measurements confirm that the S-scheme built-in electric field synergizes with ZnS vacancies to signif-icantly enhance photo-generated carrier separation and broaden the visible light response. Performance tests showed a hydrogen evolution rate of 1.75ZnS 3/CuCo PBA reaching 15.62 mmol·g-1·h-1; under 5 mM PMS, PS microplastics degradation reached 76% after 8 h with 54.8% TOC mineralization. Degradation pathway and toxicity analyses indicate SO₄·⁻ and ·OH as primary active species, facilitating ring-opening, chain scission, and deep mineralization, with significantly reduced intermediate toxicity. Theoretical analysis shows the hydrogen adsorption energy barrier approaches zero (ΔGH* = -0.13 eV), en-hancing hydrogen evolution kinetics. Mechanistic analysis reveals the ternary synergistic effects among S-vacancy, S-type heterojunction, and PMS, enabling the efficient utiliza-tion of photogenerated charges, generating a wealth of active species, thereby facilitating high-efficiency photocatalytic hydrogen production and accelerating the degradation of microplastics.

Herein, we report a targeted electronic structure reconfiguration strategy for Fe2P via precise Mo doping, producing a high-performance catalyst for both the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). The incorporated Mo atoms act as atomic-scale electron donors that transfer electron density into the Fe–P framework, forming Fe–P–Mo bonding networks that induce charge redistribution and an upshift of the Fe d-band center toward the Fermi level, thereby rebalancing the adsorption energetics of the oxygen intermediates (*O, *OH, and *OOH) toward the Sabatier optimum and lowering the energy barriers of the rate-determining steps of both the ORR and the OER. The optimized catalyst exhibits remarkable bifunctional performance, delivering a half-wave potential of 0.87 V for the ORR and an OER potential (Ej=10) of 1.56 V versus RHE at 10 mA cm−2. This yields a small potential gap (ΔE) of 0.69 V, comparable to that of the noble-metal benchmark (Pt/C + RuO2, 0.68 V). In a zinc–air battery, the catalyst achieves a peak power density of 170.2 mW cm−2 and stable cycling for more than 700 h, outperforming its Pt/C + RuO2-based counterpart (142.9 mW cm−2 and ∼140 h).

Here, we report a synergistic dimetalation strategy for the efficient synthesis of 1,2-digold(I) alkenes from alkenyl 1,2-bis(boronate) esters. In this process, the alkenyl monogold(I) intermediate readily captures a coordinatively unsaturated gold(I) species by aurophilic interactions to form a gem-digold(I) structure, which then undergoes a base-promoted 1,2-gold migration with elimination of the boronate group to afford the 1,2-digold(I) alkene in nearly quantitative yield. We proved the general applicability of this synergistic dimetalation approach by synthesizing a diverse set of 1,2-digold(I) alkenes. Upon photoexcitation, it efficiently activates the C–Cl bond of dichloromethane, generating chloromethyl radicals and causing the catalytically inactive mixed-valence gold(I)/gold(0) nanoclusters. By elucidating the aurophilic interaction-based synergistic dimetalation mechanism, this work not only provides a rational route to polymetalated organic molecules but also unveils a photoinduced pathway for C–Cl bond activation of solvent molecules, offering a new insight into the deactivation of gold(I) catalysts.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"11 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173168","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 review focuses on LiCoO2 (LCO) and emphasizes an emerging “waste-to-value” strategy: directly modifying and restructuring spent LCO into high-performance oxygen evolution reaction (OER) electrocatalysts. The formation of lithium vacancies, lattice distortions, phase transitions, and surface residues generated in spent LCO during battery long-term cycling affects the electronic structure and coordination environment of the cobalt atoms, leading to enhanced OER performance. Various modification techniques such as heteroatom doping, interface engineering, and phase reconstruction are systematically discussed. Additionally, the mechanisms of the OER process are elucidated, highlighting how different defects modulate the d-band centers, optimize the adsorption energy of oxygen intermediates, and trigger distinct reaction mechanisms. Finally, we discuss the current challenges in using spent LCO as an electrocatalyst and proposes future perspectives on its advantages, which span from half-cells to the overall water splitting process. This comprehensive review summarizes the valuable applications of converting spent LCO into electrocatalysts and provides novel insights for maximizing its residual worth.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"30 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173170","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}
