摘要：

A zeolite-imidazolium-framework-supported Pd-based heterogeneous catalyst (Pd@ZIF-8) was prepared by a metal-organic chemical vapor deposition method under mild conditions using Pd(C3H5)(C5H5) as the Pd precursor. N-2 adsorption and pore size distribution data showed that ZIF-8 and Pd@ZIF-8 both possessed high surface areas. Transmission electron microscopy images showed that Pd nanoparticles with sizes of about 1.5-3.5 nm were homogeneously dispersed on the ZIF-8 support in Pd@ZIF-8. The Pd@ZIF-8 catalyst showed good activity in Suzuki coupling reactions with several different kinds of aryl halides. It could be reused at least six times without dramatic loss of activity or decomposition of the ZIF-8 structure. (C) 2015, Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
