文摘Based on the soft-hard acid-base theory,a novel bimetallic MOF(JLU-MOF108)has been successfully synthesized through a one-pot synthesis method.JLU-MOF108 is a mixed metal-based MOF,constructed from an unprecedented hexanuclear copper cluster(12-connected),indium metal center(4-connected)and a tetrazole-containing carboxylic acid ligand(3-connected),that exhibits a(3,4,12)-connected xag topology.In order to effectively enhance the CO_(2)capture and cycloaddition catalytic performance,abundant open metal sites(OMSs),Lewis basic sites(LBSs)and specific pore sizes have been implanted in the JLU-MOF108 structure.Fascinatingly,the expected mixed metal-based MOF material has a high OMS density and suitable pore volume.The results show that JLU-MOF108 exhibits high CO_(2)adsorption performance and excellent epichlorohydrin(ECH)catalysing capability in cycloaddition reactions.More importantly,the yield of ECH can reach up to 97%,which surpasses many reported MOF materials.Therefore,JLU-MOF108 can be a good candidate material for cycloaddition reactions and CO_(2)storage.
