Highly　dispersed　palladium　nanoparticles　(Pd　NPs)　supported　on　zeolitic　imidazolate　frameworks　(ZIFs)　ZIF-8　(Pd/ZIF-8)　have　been　prepared　in　situ　via　mechanochemical　method.　The　Pd/ZIF-8　frameworks　were　characterized　by　XRD,　N-2　adsorption,　TEM,　ICP-AES　and　XPS.　The　results　show　that　bulk　production　of　highly　dispersed　palladium　nanoparticles　can　be　achieved　by　mechanochemical　method.　Moreover,　the　obtained　Pd/ZIF-8　exhibits　high　activity　for　Suzuki-Miyaura　cross-coupling　reaction　and　can　be　easily　recovered　and　reused.
