▎ 摘　　要

AucorePdshell (Au@Pd) bimetallic nanoparticles of sub-10 nm were successfully dispersed on graphene by a simple one step reducing method. The Au@Pd nanoparticles-graphene (Au@Pd-G) hybrids were characterized by high-resolution transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, energy X-ray spectroscopy and electronic energy loss spectroscopy. Evaluation of their catalytic performance demonstrates the Au@Pd-G hybrids have extraordinary peroxidase activity as catalysts.
