摘要: 采用传统浸渍法制备了不同氧化钨含量的WO3/UiO-66催化剂，利用FT-IR、XRD、N2吸附-脱附和TG测试技术对该催化剂进行了表征，并研究了其对环戊烯选择氧化制备戊二醛的催化性能。结果表明，WO3高度分散在金属有机骨架UiO-66中，WO3的引入没有改变UiO-66的结构，并适当增强了UiO-66的热稳定性。当WO3负载量为40% (w)时，WO3/UiO-66催化剂的催化性能最好，环戊烯的转化率达到92.2%，戊二醛的收率达到50.3%。
Abstract: A series of WO3/UiO-66 catalysts was prepared by the traditional impregnation method and characterized by FT-IR, XRD, N2 adsorption-desorption and TG. The catalytic activity of the catalyst was investigated for the selective oxidation of cyclopentene (CPE) to glutaraldehyde (GA). The results demonstrated that the active WO3 was dispersedly on the support UiO-66 and the skeleton structure of UiO-66 was not altered. Moreover, the thermal stability of UiO-66 was appropriately en-hanced after the introduction of WO3. The 40%(w) WO3/UiO-66 catalyst showed 92.2% of CPE conversion and 50.3% of GA selectivity.
