Abstract: Olefin epoxidation is a fundamental reaction in organic chemistry. Herein, a novel magnetic core-shell Fe3O4@Cu3(BTC)2 metal-organic framework (MOF) heterogeneous catalyst was synthesized for the use in olefin epoxidation. Additionally, the size selectivity of the Fe3O4@Cu3(BTC)2 catalyst in olefin epoxidation was investigated. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results indicated that Fe3O4@Cu3(BTC)2 presented a microsphere morphology, and Cu3(BTC)2 MOFs were well dispersed on the Fe3O4(PAA) surface after 10 cycles of the synthesis process. The synthesized magnetic core-shell Fe3O4@Cu3(BTC)2 heterogeneous catalyst could facilitate efficient aerobic olefin epoxidation. Furthermore, the catalyst was used in the aerobic oxidation of alcohols and was found to exhibit excellent activity for primary alcohols.
