| 摘 要： | 通过后修饰水热合成法制备了新型Co2+配位的金属有机框架材料，并采用红外、电感耦合等离子分析和N2吸附等技术手段对其进行了表征。 在氧气/异丁醛反应体系中，介孔钴金属有机框架对烯烃环氧化反应表现出较高的活性。 其中，环辛烯的转化率及环氧环辛烷的选择性分别达到了94%和91%,转化频率(TOF)值为509 h-1。 催化剂循环使用5次之后，其结构和活性无明显变化。

| 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 InductivelyCoupledPlasma. 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. |
