However, due to the high production cost for synthesizing silver nanoparticles, an alternative nanomaterial such as copper nanoparticles that have lower cost and good conductivity to replace silver nanoparticles is used to replace silver nanoparticles. In order to prevent the oxidation of copper nanoparticles, the formation of a silver shell on the external surface of copper nanoparticles as protective layer has been highly demanded. Here, we use a transmetallation method to successfully synthesize the copper/silver core/shell nanoparticles. The obtained copper/silver core/shell samples are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive (EDS), and high-resolution transmission electron microscopy (HR-TEM) to prove the formation of the core/shell structure. The synthesized copper/silver core/shell nanoparticles would be potential for application of inkjet printing in the future. Copyright ? 2016 American Scientific Publishers. |
