Ru(II) and Pt(II) complexes are among the most investigated compounds as potential photosensitizers for photodynamic therapy based on their outstanding photophysical and biological properties (i.e., strong emission, high intersystem crossing efficiency, large Stokes shift, high (photo-)stability, biological compatibility, good water solubility). While these classes of compounds have been widely studied separately or combined in derivatives that display a dual therapeutic effect, herein, a novel study on the conjugation of Ru(II) and Pt(II) fragments into a single bimetallic conjugate is proposed. It is assumed that this molecular design could undergo an intramolecular electron transfer from the Ru(II) moiety to the Pt(II) moiety upon irradiation to produce a highly efficient excited state. Capitalizing on the presence of both metals, the bimetallic conjugate was found to generate singlet oxygen with an outstanding efficiency in comparison to its individual components. To enhance the pharmacological profile, the bimetallic complex was encapsulated into polymeric nanoparticles. The nanoparticles were demonstrated to eradicate human breast adenocarcinoma monolayer cells as well as multicellular tumor spheroids upon light irradiation at nanomolar concentrations. We are confident that this approach will open new avenues towards the development of novel highly efficient photosensitizers.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"67 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920729","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 report a methyl-modified heptanuclear cluster-based MOF, Ni7Me, constructed from inexpensive organic linkers under pure water conditions. Two guest-free materials, Ni7Me-80 (with coordinated water) and Ni7Me-200 (with OMSs), were synthesized to investigate the separation properties and mechanisms for C2H2/C2H4 and C3H6/C3H8 mixtures. Dynamic breakthrough tests showed that both Ni7Me-80 and Ni7Me-200 could achieve clean separation of binary C2H2/C2H4 mixtures (5/95 v/v), yielding high-purity C2H4 (>99.9%). Grand canonical Monte Carlo (GCMC) simulations revealed that the enhanced adsorption and separation performance of Ni7Me-200, compared to Ni7Me-80, is primarily due to differences in the interaction forces between C2 molecules and the framework, independent of the OMSs. Notably, Ni7Me-80 exhibited thermodynamically driven adsorption for C3H6, while showing kinetic behaviour for C3H8 adsorption. This unique property enabled effective separation of C3H6 and C3H8, as demonstrated by dynamic permeation tests. Stability tests further showed that Ni7Me has exceptional air and boiling water stability.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915821","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}

Although numerous single compounds exhibit certain electrocatalytic properties, their inherent limitations hinder optimal performance. In this article, a highly active electrode was synthesized by constructing a heterojunction between Fe2(MoO4)3 and Ni(OH)2. As expected, the Ni(OH)2/Fe2(MoO4)3@TM heterojunction catalytic electrode demonstrated remarkable activity for water oxidation in a 1.0 M KOH electrolyte, exhibiting a low overpotential of 265 mV (at 10 mA cm-2 current output) while maintaining excellent stability. This superior performance was validated through electrochemical tests, DEMS, TEM, Raman spectroscopy and DFT calculations. The results indicate that the constructed heterojunction electrode, due to its synergistic effect, optimizes the d-band center, modulates the adsorption energies of *OH and *O at the electrode interface, facilitates electron transfer and surface reconstruction of the catalyst, and thereby enhances OER activity and stability.

Copper (Cu) is considered as one of the most effective catalysts for electrocatalytic CO2 reduction reaction (CO2RR). However, its utilization potentiality is limited by poor selectivity for hydrocarbon products and the competing hydrogen evolution reaction (HER). In this study, we present a strategy to suppress the HER process and enhance the CH4 selectivity of large-scale Cu foil toward CO2RR. By coating the Cu foil surface with a porous polyaniline (PANI) layer, the H2 Faradaic efficiency (FE) reduces from 60% to 18%. Moreover, the FE of hydrocarbons increases dramatically from 25% to 80%, and the FE of dominant product CH4 is high up to 62%. The in situ electrochemical attenuated total reflection Fourier transform infrared spectroscopy (in situ ATR-FTIR) and density functional theory (DFT) calculations are conducted to elucidate the mechanism. The enhanced performance of Cu-PANI in CO2RR is mainly attributed to the porous PANI layer, which facilitates CO2 adsorption and mass transport. This leads to a reversal in the energy barrier for the rate-determining steps between HER and CO2RR, significantly inhibiting HER and enhancing CO2RR activity. Additionally, Cu-PANI promotes the hydrogenation of *CO to *CHO, resulting in higher methane selectivity. This work provides a promising strategy for designing efficient large-scale Cu-based catalysts with high CH4 catalytic activity and selectivity.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"74 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903002","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}
