Abstract

Here we report a magnetic composite nanocatalyst (MP@NiSiO/Pd) with a rattle type nanostructure. The nickel silicate shell encapsulated magnetic core (MP@NiSiO) rattle particles were synthesized by using a facile templating method and the Pd nanocrystals with different sizes can be directly immobilized onto the MP@NiSiO rattles without using any surfactant or capping reagents. X-Ray powder Diffraction (XRD) and Transmission Electron Microscopy (TEM) are employed to characterize the rattle type particles. The MP@NiSiO/Pd composites show catalytic activity on the Heck and Suzuki reactions. They can be separated from the reaction system by using a magnet and the catalyst can be cycled at least for 5 times.
