Abstract

ABSTRACT We report a facile protocol for the one-pot preparation of monodisperse Pd nanoparticles (NPs) supported on ultrathin NiCl2 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.
