通过简单的一步还原方法，成功地将亚 10 nm 的 AucorePdshell (Au@Pd) 双金属纳米颗粒分散在石墨烯上。通过高分辨率透射电子显微镜、扫描电子显微镜、X射线光电子能谱、X射线衍射、能量X射线能谱和电子能量损失谱对Au@Pd纳米颗粒-石墨烯（Au@Pd-G）杂化物进行了表征。对其催化性能的评估表明，Au@Pd-G 杂化物作为催化剂具有非凡的过氧化物酶活性。
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.
