This study addresses the preparation of epitaxial Co₉S₈ thin films with orientations of (100), (110), and (111) on yttrium-doped zirconia (YSZ) substrates using pulsed laser deposition. Characterization confirmed their single-crystalline nature and consistent thickness. Electrochemical measurements revealed a similar hydrogen evolution reaction (HER) performance across all films but significant differences in the oxygen evolution reaction (OER) performance. The (111) orientation showed the best OER activity, with a current density of 24.2 mA cm^–2 at 1.8 V vs RHE, outperforming the (100) and (110) orientations, which achieved 14.5 and 6.7 mA cm^–2, respectively. Density functional theory (DFT) calculations indicated that the (100) orientation favored the traditional four-electron transfer mechanism, with a lower theoretical overpotential (0.37 V). In contrast, the (110) and (111) orientations demonstrated more complex adsorption behaviors, resulting in a higher overpotential of 0.49 V and a lower overpotential of 0.29 V, respectively.

These structures offer immense potential for enhancing light harvesting and tuning the localized surface plasmon resonance (LSPR). However, the lack of a universal and scalable synthetic method for constructing diverse semiconductor shells remains a major challenge. In this study, we report for the first time a versatile low-temperature two-step method for fabricating hollow gold nanoparticles (HGNs)@semiconductor core–shell heterostructures. By employing mercaptobenzoic acid (MBA) as a linker molecule and polyvinylpyrrolidone (PVP) as a stabilizing agent, this method enables the uniform deposition of various semiconductors, including CuO, Fe₃O₄, CdS, FeS, and Ni(OH)₂. The method exhibits broad material applicability and allows precise control of LSPR by adjusting the semiconductor shell thickness, spanning a spectral range from the visible to the near-infrared (NIR) region. Our work not only demonstrates the modulation of LSPR properties through shell thickness but also provides new insights into the metal–semiconductor interfacial dynamics and plasmonic energy transfer mechanisms. This versatile synthetic platform not only lays the foundation for next-generation photocatalysts and optoelectronic devices in the visible and NIR regions but also broadens its potential applications to other metal@compound core–shell systems across fields, such as optoelectronics, energy, and catalysis.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"67 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545898","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}

However, the adverse surface oxygen lattice evolution caused by irreversible ARR tends to lead to poor cyclic stability and severe voltage decay, which limits its commercial application. In this work, using Na_0.67Mn_0.5Fe_0.5O₂ (NMFO) as the model compound, an optimization strategy by modulating surface oxygen coordination through a simultaneous surface Li doping and Li₃PO₄ coating is proposed to achieve both triggered and reversible ARR processes. As revealed by neutron diffraction techniques and transmission electron microscopy tests, Li ions and Li₃PO₄ are successfully doped and coated on the surface of the NMFO cathode, respectively. The optimized cathode expectedly shows not only enhanced specific capacity but also improved cyclic stability. The excellent electrochemical properties are ascribed to the suppressed detrimental P2–O2 phase transition, enhanced ARR reversibility, and improved thermal structural stability. More broadly, this work demonstrates the feasibility of modulating surface oxygen coordination to activate and stabilize the ARR ion-storage process.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"36 8 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539174","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}

This interaction can modify the surface adsorption state, electronic structure, and coordination environment of the supported metal, altering the interface structure of the catalyst. These changes serve to enhance the catalyst’s activity, stability, and reaction selectivity. In recent years, a multitude of researchers have uncovered a range of novel SMSI types and induction methods including oxidized SMSI (O-SMSI), adsorbent-mediated SMSI (A-SMSI), and wet chemically induced SMSI (Wc-SMSI). Consequently, a systematic and critical review is highly desirable to illuminate the latest advancements in SMSI and to deliberate its application within heterogeneous catalysts. This article provides a review of the characteristics of various SMSI types and the most recent induction methods. It is concluded that SMSI significantly contributes to enhancing catalyst stability, altering reaction selectivity, and increasing catalytic activity. Furthermore, this paper offers a comprehensive review of the extensive application of SMSI in the electrocatalysis of hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), and carbon dioxide reduction reaction (CO₂RR).

However, the generation of H₂O₂ through a single-channel oxygen reduction reaction (ORR) is prevalent, while the water oxidation reaction (WOR) is frequently neglected. Herein, we constructed Z-scheme ZnIn₂S₄/UiO66-NH₂ (ZIS/UNH) heterojunctions, integrating the ORR and WOR dual pathways for photocatalytic H₂O₂ generation without noble cocatalysts and sacrificial agents. The optimized ZIS/UNH exhibits the highest H₂O₂ yield of 0.85 mmol g^–1 h^–1, which is 2.2 and 14 times those of ZIS and UNH, respectively. The formation of the Z-scheme heterojunction efficiently promotes the separation and transfer of photogenerated carriers while retaining holes with high oxidizing ability and electrons with strong reducing ability. The free radical quenching and DMPO-ESR radical trapping experiments demonstrate that the ZIS/UNH heterojunctions produce H₂O₂ in a dual-channel mode different from the single-channel ZIS. The pathways for H₂O₂ generated by ZIS/UNH consist of a two-step single-electron ORR with ·O₂^– as an intermediate product and a direct one-step WOR.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"12 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545914","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}

Adsorption on minerals is considered as a major factor in governing tungsten’s mobility and bioavailability. Goethite, a highly stable iron oxide in soils and sediments, is pivotal in determining tungsten’s environmental behavior. In this study, the sorption mechanisms of tungsten on the primary (110) surface of goethite were investigated by using systematic first-principles molecular dynamics (FPMD) simulations. First, we computed the bidentate corner-sharing complexation structures of tungsten in all protonation states (i.e., WO₄^2–, HWO₄^–, and H₂WO₄⁰) on the goethite surface. Tungsten exhibits a fivefold coordination in the WO₄^2– and HWO₄^– systems, whereas it transforms into a sixfold coordination in the H₂WO₄⁰ system. By using the vertical energy gap method for p<i>K</i>_a calculations, it is revealed that the adsorbed WO₄(H₂O)^2– species is predominant at pH &gt; 2.0, which is different from WO₄^2– in aqueous solutions (pH &gt; 4.9). The desorption free energy of WO₄(H₂O)^2– species suggest that the bidentate corner-sharing form of WO₄(H₂O)^2– is highly stable with a binding energy of 19.8 kcal/mol. This study fills a critical gap in the atomic-scale knowledge of tungsten behavior and stability in natural environments, providing a theoretical foundation for managing tungsten mobilization in both natural and industrial settings.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"17 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539073","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}

The molecular ESP distributions of Cd-DBDP and RNA-related nucleotides were calculated and employed to predict the sensing results. Fluorescence tests demonstrated that Cd-DBDP represents the first example of an MOF-based sensor for guanosine diphosphate (GDP) sensing, and the experimental observations were highly consistent with the theoretical prediction. The sensing mechanism for GDP was thoroughly studied through Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy/energy-dispersive spectroscopy (SEM/EDS), X-ray photoelectron spectroscopy (XPS), and theoretical calculations. These findings provide valuable insights into understanding the interplay between the molecular ESP distribution condition and the sensing results.

The coordination self-assembly of Co^II salts and 8-quinolinesulfonic acid ligands affords a mononuclear Co^II sulfonate featuring both coordinated and noncoordinated sulfonic acid O atoms and axial coordinated water molecules.
