摘要

We report a facile protocol for the one-pot preparation of monodisperse Pd nanoparticles (NPs) supported on ultrathin NiCla nanosheets (NSs).The effective protocol can be described as in situ reduction-oxidation-assembly to create Pd/NiCl2 nanocomposites and is applicable for the development of stable yet highly active Pd-based heterogeneous catalysts for organic transformations.The Pd/NiCl2 composite displayed synergistically enhanced catalytic activity,high stability,and good recyclability for the tested model oxidation reaction.The in situ nucleation and growth of NiCl2 NS around Pd NPs guaranteed a clean metal-support interface and greatly facilitated the catalytic reaction.This work provides a novel synthesis method for supported Pd nanocomposites suitable for many important applications.
