In this study, a novel mechanochemistry approach was developed to convert stoichiometric MgO and Co2O3 into MgCo2O4. This innovative synthesis involved a one-step ball milling process that integrates two reaction steps. Initially, MgO reacted with water to form Mg(OH)2, followed by migration of Mg ions from Mg(OH)2 into Co2O3 lattice to generate MgCo2O4. The milling parameters were optimized to enhance the conversion efficiency of MgCo2O4 through X-ray Diffraction analysis. Complete conversion of MgCo2O4 was achieved with a single batch production capacity of 100 g, using a ratio of water volume to reactant weight of 2.0 mL/g, a ball-to-powder ratio of 10:1, a revolution speed of 350 rpm, and a milling time of 80 hours. The synthesis mechanism was elucidated using X-ray Photoelectron Spectroscopy. The synthesized MgCo2O4 particles exhibited a small particle size of 117.8 nm and a high specific surface area of 63.3 m²/g, based on these properties, the electrode exhibited a notable specific capacitance of 665.8 F/g at 0.1 A/g, highlighting its potential as an excellent active material for supercapacitor electrodes. This study demonstrates a facile, green, cost-effective, and scalable production method for MgCo2O4, promoting its application in electrochemical energy storage.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142276099","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 typical BCPS comprises silica colloidosomes containing co-catalysts as microreactors, where positively charged N- methyl-4-cyanopyridinium (MCP+) serves as the electron carrier. The MCP+ molecules harvest energy from photoexcited g-C3N4, and transit to electrically neutral species MCP0, which can pass the colloidosome. Driven by the light, the MCP0 diffusion across the membrane, using Pt co-catalysts to transport electrons to H+ to produce hydrogen. Analogous to natural photosynthesis, hydrogen evolution occurs within compartments, separating light and dark reactions, protecting the dark reaction from interference during light harvesting and minimizing potential side effects. The system enables sustained evolution of hydrogen with a higher yield than the control catalysis in a bulk catalyst suspension. The dramatic influence of SDS on the hydrogen evolution was revealed, and a possible mechanism of electron carrier amount buffering was proposed.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142245826","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 article, density functional theory calculations indicate that the Ba0.5Pb0.5S alloy possesses desirable optoelectronic properties, including a direct bandgap (1.75 eV), a high optical absorption coefficient, and high defect tolerance. Experimentally, we developed a dibutyldithiocarbamate (DBuDTC) solution process for synthesizing Ba0.5Pb0.5S polycrystalline powders and thin films using a discrete molecular precursor strategy. Additionally, atomic-resolution scanning transmission electron microscopy provided invaluable insights into the Ba0.5Pb0.5S alloy structure. Moreover, the bandgap of Ba–Pb–S ternary alloys can be adjusted, and they exhibit outstanding storage stability under high-humidity conditions. These favorable optoelectronic properties position Ba–Pb–S alloy materials as excellent candidates for both solar energy conversion and optoelectronic materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142245825","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 study, the two-dimensional network structure [Zn(L3)·H2O]n (ZnL, L=5-aminoisophthalic acid) was firstly successfully prepared by a simple solvothermal reaction. Then, nitrogen-doped carbon coated ZnSe nanoparticle composites (denoted as ZnSe@NC) were obtained by salinization of ZnL. Benefiting from the synergistic effect of ZnSe nanoparticles and NC, ZnSe@NC demonstrated ultra-long cycling stability (a capacity decay rate of only 0.052% per cycle) and high rate performance (400.6/311.1 mAh g−1 at 0.1/10 A g−1). The excellent electrochemical properties of ZnSe@NC can be attributed to high pseudocapacitance contribution, low charge transfer impedance, and high ion diffusion coefficient. In addition, ex-situ XRD, XPS, and HRTEM analysis revealed that the sodium storage process of ZnSe@NC is a conversion reaction followed by an alloying reaction. More importantly, the sodium-ion full battery Na3V2(PO4)3@rGO//ZnSe@NC can maintain a reversible capacity of 216.4 mAh g−1 after 100 cycles at 0.3 A g−1.

Nonmetal and metal element codoping is an effective way to profoundly modulate the electronic structure of transition metal oxide catalysts and the interaction with oxygen (O) adsorbates, which are crucial forOER efficiency. Herein, a sulfur (S), phosphorus (P) and iron (Fe) element codoped nickel oxide (NiO), denoted as S,P-NiO(Fe), was prepared as an OER catalyst, wherein the incorporation of P and Fe played significant roles in regulating the electronic structure of the NiO motif and reducing the activation barrier of the rate-determining step (RDS) during the OER process, thus substantially enhancing the catalytic capability. Concretely, the S,P-NiO(Fe) electrode displayed an overpotential of 230 mV at an OER response of 50 mA cm−2, a low Tafel slope of 64 mV dec−1 and robust catalytic stability. Theoretical calculations showed that the incorporation of P and Fe downshifted the d-band center position, which mediated the adsorptive interaction strengths of O-intermediates and reduced the activation barrier of the RDS (from *O to *OOH), whereupon the low energy pathway led to rapid OER kinetics. This work offers a viable tactic to improve the OER catalytic capability of metal oxides through metal and nonmetal element codoping.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236677","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}

Everyone knows that the indium atom has a relatively large radius, and is environmentally friendly. Importantly, the In(III) cation has a unique electronic configuration with a high cyclic p-block, allowing it to form strong coordination bonds with atoms such as O, N, and S in the presence of a variety of Lewis acids. Therefore, the constituted stable In-MOFs with various structural types and chemical properties are worthy of systematic study. To better comprehend the future research trend of In-MOFs, it is necessary to evaluate their recent research progress thoroughly. Furthermore, this analysis of In-MOFs will fill gaps in the current literature, and we believe that a thorough review of such MOFs would be extremely valuable to future research. Note that we mainly review these MOFs since In-MOFs in the literature are mainly constructed by carboxylic acid ligands. In this review, we will conclude the preparation methodologies, structural peculiarities, and numerous uses of MOFs composed of indium(III) nodes and various connections, as well as present and future possibilities.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236684","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}

Herein, we explore structural variations of AlHAl obtained by replacing the PhNMe2 (DMA) donor with a variety of anilines, amines, and N-heterocycles. Of the 18 investigated N-donors, twelve provided stable AAB salts; those were tested as cocatalyst in ethylene/1-hexene copolymerization with a archetypical metallocene catalyst. In the other six cases, occurring side reactions were thoroughly analyzed by NMR spectroscopy. For instance, addition of an o-Me substituent on the DMA ligand triggers C–H activation leading to five-membered cyclometalated species; increasing steric bulk directly at the N-donor atom leads to tricoordinate mononuclear Al-alkyl cations, which could be isolated, fully characterized and tested in polymerization when using PhNEt2 (DEA). Cocatalytic performance of aniline- and amine-based systems varies only marginally with respect to the benchmark AlHAl_DMA. N-heterocyclic AAB salts perform worse; only the two least electron donating donors, namely difluoropyridine (Py-3,5-F) and quinoline (QUI) provide noticeable productivity.

Leveraging density functional theory and machine learning, we herein reveal the synergism between metal single atoms (M-SAs) and S-vacant two-dimensional (2D) MnPS3 nanosheets (Sv-MnPS3). Specifically, M-SAs occupy S-vacancies and activate the neighboring S sites as new active sites for the HER. In turn, Sv-MnPS3 improves the ability of metal-SAs for water dissociation by modulating their magnetic moments. During the HER, H* is generated on metal-SAs and then migrates to neighboring S sites on which H2 is produced, representing catalytic synergism via hydrogen spillover. Among the M1/Sv-MnPS3 candidates, Pd1/Sv-MnPS3 possesses an optimal ΔGH* of 0.01 eV and is both thermodynamically and electrochemically stable. Therefore, the synergism between Pd1 and Sv-MnPS3 enables Pd1/Sv-MnPS3 to be active and durable for the HER.
