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.
