A novel strategy for producing highly dispersed Pd particles on ZIF-8 through the occupation and unoccupation of carboxyl groups and its application in selective diene hydrogenation
We proposed a novel strategy for producing highly dispersed Pd particles on ZIF-8 via the anchoring effect of the carboxyl groups incorporated into the ligand of ZIF-8. The as-synthesized Pd nanoparticles supported on the in situ carboxyl-functionalized ZIF-8 showed excellent activity and selectivity for diene hydrogenation due to the high dispersion of Pd nanoparticles and the interaction between the Pd nanoparticles and carboxyl groups. This method opens a new and simple route for greatly improving the dispersion of supported Pd nanoparticles. (C) 2015 Elsevier Inc. All rights reserved.
