2026-05-29 Study on Bimetallic Cu/Ni-MOFs Catalysts for Cycloaddition Reaction of Carbon Dioxide with Epoxides doi:10.57760/sciencedb.38447 en Monometallic metal-organic framework (MOF) catalysts (Cu-MOFs and Ni-MOFs) and bimetallic Cu/Ni-MOFs catalyst were fabricated via a solvothermal method. The as-prepared three catalysts were systematically characterized by XRD, XPS, HADDF-STEM-EDS, FT-IR, and other analytical techniques. Meanwhile, the catalytic performances of the three catalysts were investigated in the cycloaddition reaction of styrene oxide with CO2. The results revealed that bimetallic Cu/Ni-MOFs exhibited outstanding catalytic performance with a conversion of 93% and selectivity of 99%, which was remarkably superior to those of monometallic Cu-MOFs (58% conversion, 99% selectivity) and Ni-MOFs (69% conversion, 99% selectivity). The enhanced catalytic activity was mainly attributed to the synergistic effect between Cu2+ and Ni2+ bimetallic ions, which effectively regulated the electronic structure of the catalyst and improved the catalytic activity and stability of active sites. Furthermore, substrate scope experiments verified that the Cu/Ni-MOFs catalyst possessed excellent catalytic activity and selectivity toward the cycloaddition of various styrene oxide derivatives with carbon dioxide, demonstrating great application potential. metal-organic frameworks; Cu/Ni-MOFs catalyst; carbon dioxide; cycloaddition Zhang Lulu Qi Pengcheng Shi Jing PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset http://www.doi.org/10.3724/j.issn1001-3555.2026.03.004 Science Data Bank
