Abstract
A series of different amount of Pd nanoparticles were successfully loaded on the metal-organic frameworks UiO-66-NH2 using a simple solution impregnation method and applied as efficient catalysts for epoxidation of styrene. In this work, the best reaction efficiency can be explored by altering Pd loadings of Pd/UiO-66-NH2, solvents, reaction temperatures and the molar ratios of styrene to tert-butyl hydroperoxide. Interestingly, when Pd loadings of Pd/UiO-66-NH2 is 3.69 wt%, the target product can be obtained in high yield and selectivity.
