Preparation of MoO2(acac)2@MIL-101 and Its Catalytic Performance
摘要: 以金属-有机骨架MIL-101为载体、以乙酰丙酮钼(MoO2(acac)2)为活性组分，采用溶剂回流方法将MoO2(acac)2引入MIL-101孔道中合成新型催化剂MoO2(acac)2@MIL-101，考察了MoO2(acac)2@MIL-101对大豆油环氧化反应的催化性能，并利用多种测试技术对该催化剂进行了表征(FT-IR、XRD、SEM、N2吸附和UV-Vis-DRS)。研究结果表明：MoO2(acac)2高度分散在MIL-101孔道中，MoO2(acac)2的引入没有改变载体的形貌和骨架结构。具有较大比表面积和孔容，且含有适量的、高度分散的活性组分的MoO2(acac)2@MIL-101催化剂对大豆油环氧化反应显示出良好的催化活性和重复使用性能。
Abstract: MoO2(acac)2@MIL-101 was prepared by the organic solvent-internal reflux method using MIL-101 and MoO2(acac)2 as the support and the active species, respectively. From the results of characterizations of the catalysts by XRD, FT-IR, N2 adsorption and UV-Vis-DRS techniques, it is concluded that the special morphologies and crystalline structure of MIL-101 could be well kept and MoO2(acac)2 was highly dispersed into the mesoporous cages of MIL-101. The 25%(w) MoO2(acac)2@MIL-101 catalyst shows good catalytic activity for the epoxidation of soybean oil, which has high specific surface area and pore volume and high dispersed active species MoO2(acac)2.
