The catalytic activity of the catalyst was investigated for the selective oxidation of cyclopentene (CPE) to glutaraldehyde (GA). The re- sults 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 enhanced after the introduction of WO . The 40%(w) WO /UiO-66 catalyst showed 92.2% of CPE 3 3 conversion and 50.3% of GA selectivity.
