In this paper, the palladium nanoparticles were successfully encapsulated in metal-organic framework material, UiO-66, by a facile approach. Based on the microwave-assisted method, the pores of UiO-66 were activated and the metal precursors were reduced at the same time in the presence of reducing agent. The obtained Pd@UiO-66 was characterized via transmission electron microscopy, powder X-ray diffraction, N-2 adsorption and X-ray photoelectron spectroscopy. The Pd@UiO-66 exhibited efficient catalytic activity for the Suzuki-Miyaura coupling reactions at mild condition. [GRAPHICS] .
