摘要
Olefin epoxidation is a fundamental reaction in organic chemistry.Herein,a novel magnetic core-shell Fe_(3)O_(4)@Cu_(3)(BTC)_(2) metal-organic framework(MOF)heterogeneous catalyst was synthesized for the use in olefin epoxidation.Additionally,the size selectivity of the Fe_(3)O_(4)@Cu_(3)(BTC)_(2) catalyst in olefin epoxidation was investigated.Scanning electron microscopy(SEM)and transmission electron microscopy(TEM)results indicated that Fe_(3)O_(4)@Cu_(3)(BTC)_(2) presented a microsphere morphology,and Cu_(3)(BTC)_(2) MOFs were well dispersed on the Fe_(3)O_(4)(PAA)surface after 10 cycles of the synthesis process.The synthesized magnetic core-shell Fe_(3)O_(4)@Cu_(3)(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.
