In this study, we synthesized two semiconductor hybrid Cd/Hg-selenidostannates, (H2BPP)2CdSn3Se9 and (H2DMP)2Hg4Sn4Se17, employing 1, 3-bis(4-piperidinyl) propane and 1, 5-diamino-2-methylpentane through a surfactant-assisted thermal method. Remarkably, these hybrid chalcogenides are highly soluble in DMF, facilitating the formation of smooth, pinhole-free thin films via spin-coating method. (H2BPP)2CdSn3Se9 and (H2DMP)2Hg4Sn4Se17 films exhibit exceptional stability under high humidity and heat, with semiconducting band gaps of 2.12 eV and 2.21 eV, respectively. These band gaps enable strong light absorption and charge carrier generation, which directly contribute to their significant photocurrent responses. Specifically, Photocurrent measurements show Ilight of 1.5 µA cm⁻² and 1 µA cm⁻² at 0.8 V for (H₂BPP)₂CdSn₃Se₉ and (H₂DMP)₂Hg₄Sn₄Se₁₇, notably higher than the 0.30 mA cm² observed for the commercially available SnSe₂ electrode under the same conditions. Building on these interesting electrical properties, (H2BPP)2CdSn3Se9 also showed notable piezoelectric properties, resulting from its unique structural framework that supports both efficient charge transport and mechanical responsiveness. These promising stability and multifunctional characteristics highlight the potential of these hybrid selenidostannates for advanced optoelectronic and piezoelectric applications.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"34 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767018","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}

Effectively manipulating the local reaction environment could provide a promising solution. Here, we report a Brønsted base silicate (SiO₃²⁻)-modified NiFe(OH)x catalyst. As a proton acceptor, Brønsted base SiO₃²⁻ accelerates the cleavage of OH-H bonds at Ni/Fe sites (*H2O → *OH + H+ + e−), thereby facilitating *OH accumulation and enhancing the local *OH-enriched reaction environment. With these advantages, the optimized NiFe(OH)x-SiO32- catalyst exhibits a low OER overpotential of 280 mV at 10 mA cm⁻², a 150 mV reduction compared to the unmodified NiFe(OH)x catalyst. Furthermore, the membrane electrode assembly electrolyzer using NiFe(OH)x-SiO32-||Pt/C achieves an energy conversion efficiency of 69.2% and a current density of 1.0 A cm⁻² at 1.81 V, maintaining stable performance over 240 hours with a negligible degradation. The strategy of Brønsted base SiO₃²⁻ modification offers a promising and cost-effective approach for enhancing the efficiency of neutral water electrolysis.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"32 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758345","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 leverage a carbonyl-free metal-metal salt metathesis protocol to access rare examples of low-valent tantalum/gold multimetallics. The initial reaction between [Ta(naphthalene)3]– and gold(I) synthons affords a trimetallic monohydride cluster (2). Whereas dihydrogen addition to 2 results in deauration en route to a Ta-µH2-Au complex (1), oxidative transformations—either addition of chemical oxidants or cluster protonation—conserve the trimetallic core, even in the absence of a polynucleating ligand. The resultant series of compounds provide experimental anchors for computational interrogation of polarized metal-metal interactions as a function of metal identity, formal oxidation state, and ligand sphere. The electronic structure of these clusters showcases significant Ta-arene covalency, even at higher oxidation states, rationalizing a recalcitrance to undergo ligand substitution. Furthermore, the addition of in situ generated Au+ to2 results in an arene C–H activation process, highlighting that the naphthalene ligands in these complexes are simultaneously substitutionally inert and prone to functionalization.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"101 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766571","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}

However, using MHPs as photocatalysts for photocatalytic toluene oxidation is rare and the underlying mechanisms affecting toluene oxidation are still unclear. In this article, we constructed two novel one dimensional (1D) Ferrocene-based Perovskites catalysts, (C13H17FeNH)PbI3 and (C13H17FeNH)PbI3•DEF, in which (C13H17FeNH)PbI3 can photocatalyze the oxidation of toluene to benzaldehyde effectively. It's interesting that the crystal lattice of (C13H17FeNH)PbI3 and (C13H17FeNH)PbI3•DEF can be converted to each other through the gain and loss of solvent molecules, which not only regulates the electronic band structure, but also increases the separation efficiency of photogenerated carriers. These results were confirmed by the steady-state photoluminescence (PL), the time-resolved photoluminescence (TRPL) spectra, transient photocurrent responses measurements and density functional theory (DFT) calculations. In addition, the lower exciton binding energy (43.2 meV) of (C13H17FeNH)PbI3 further demonstrates its effective carriers’ separation efficiency. Furthermore, the selective adsorption of (C13H17FeNH)PbI3 on toluene and benzaldehyde provides a prerequisite for the efficient selective oxidation of toluene. Finally, (C13H17FeNH)PbI3 exhibited excellent catalytic activity for the photocatalytic oxidation of toluene to benzaldehyde with conversion of 28.5% and the selectivity (95.3%) towards benzaldehyde.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"97 6 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758348","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 designed an organic-inorganic hybrid material (LDH-Vo@PANI) as the cathode for efficient NH4+ storage via interface engineering and defect engineering. The polyaniline coating enhanced the structural stability of NiCo-LDHs by constructing Ni/Co-N bonds, which inhibited their dissolution during charging and discharging. The oxygen vacancies effectively buffered the electrostatic interaction between NH4+ and NiCo-LDHs, thereby increasing the diffusion rate of NH4+. Furthermore, density functional theory (DFT) calculations strongly demonstrate the positive effects of PANI coating and oxygen vacancies on the NH4+ adsorption capacity and conductive properties of the electrode material. Therefore, the LDH-Vo@PANI exhibits an area capacitance of up to 2091 mF cm-2 at 1 mA cm-2 while maintaining a high rate performance of 55.8%. The assembled supercapacitor exhibits an ultra-high energy density of 75 Wh kg-1 and a power density of 788 W kg-1 and maintains 99.48% initial capacitance retention and 100% Coulomb efficiency after 10,000 cycles.

The experimental and density functional theory (DFT) calculations disclose that the introduction of CoS into MoS2 not only can promote initial H2O adsorption/dissociation process and optimize Gibbs free energy of hydrogen adsorption (ΔGH*), but also induce the fast transfer of the adsorbed hydroxyl, thus avoiding the blocking and poisoning of the active sites. Accordingly, MCS-1 exhibits remarkably enhanced HER performances with lower overpotentials of 64 and 149 mV at 10 and 100 mA cm−2. More importantly, by using MCS-1 as both the cathode and anode to assemble AEMWE device, which can achieve a current density of 200 mA cm−2 at a low voltage of 1.63 V, and stable operation over 500 h in alkaline media.

Several studies have demonstrated the behavior in the ground state when irradiated with light. However, much remains to be discovered about the chemistry of photoCORMs with uncoordinated ligand moieties and the excited states of these compounds. This research fills that gap via the synthesis, characterization, and study of the excited states of five manganese(I) complexes containing a potentially bi- or tridentate ligand framework (κn- Se,N,Se; n=2,3). The obtained compounds, [Mn(κ2-L)(CO)3Br], retain a uncoordinated selenium-donor moiety. CO-release assays using violet light revealed the formation of a biscarbonyl intermediate. TD-DFT calculations showed that in [Mn(κ2-L)(CO)3Br], the first two excited states are involved. Generalized Kohn-Sham energy decomposition analysis indicated that the strongest metal-carbonyl interaction in the ground state (carbonyl trans to bromide) became the weakest in the excited state. DFT calculations confirmed the coordination of free selenium upon CO loss, forming [Mn(κ3-L)(CO)2Br], for which two configurational isomers (meridional and facial) may occur, with the first being more favored. The total interaction energies of the two carbonyls are similar, indicating the release of both.

The experimental results disclose that the linker engineering, by changing the heteroatoms and conjugation systems from benzooxadiazole, benzothiadiazole, benzoselenadiazole, naphthothiadiazole, to naphthoselenadiazole, tunes the electron-accepting capacity of corresponding D-A COFs.
