Abstract:  A newly Co2+ coordinated metal-organic framework had been successfully synthesized via one-step post-functionalization hydrothermal method and characterized through Fourier Transform Infrared Spectrometer, N2 adsorption and Inductively Coupled Plasma. Using O2 as oxidant, mesoporous cobalt metal-organic framework was investigated as a good performed heterogeneous catalytic material for various olefins epoxidation. Among them, the conversion of cyclooctene and selectivity of epoxycyclooctane were 94% and 91%, respectively, the turnover frequency was 509 h-1. The PCN-100(Co) exhibited excellent stabilities in 5 recycles without any loss of its catalytic performance.
