Research shows that bimetallic nanocomposites have important potential applications. In this paper, a method of synthesizing Cu-Ag bimetallic nanoparticles loaded on reduced graphene surface composite at room temperature by using mild solvent is introduced. After characterization, such as Scanning Electron Microscope (SEM), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM) and X-ray photoelectron spectroscopy (XPS), it was found that a large number of Cu-Ag nanoparticles with core–shell structure dispersed on the surface of reduced graphene oxide (rGO). The Cu-Ag NPs/rGO nanocomposite contributed to superior electrical properties for reduction of H₂O₂ compare to Cu NPs/rGO or Ag NPs/rGO.

研究表明，双金属纳米复合材料具有重要的潜在应用。本文介绍了一种在室温下用温和溶剂合成负载在还原石墨烯表面复合材料上的Cu-Ag双金属纳米粒子的方法。通过扫描电子显微镜（SEM），X射线衍射（XRD），透射电子显微镜（TEM）和X射线光电子能谱（XPS）等表征后，发现大量具有核的Cu-Ag纳米粒子–分散在氧化石墨烯（rGO）表面的壳结构。与Cu NPs / rGO或Ag NPs / rGO相比，Cu-Ag NPs / rGO纳米复合材料有助于降低H ₂ O _2的优异电性能。
