| Abstract: | Nano-copper was synthesized by copper sulfate,and Cu/Ag nanoparticles were prepared by deposition of Ag through chemical reduction,then the process of reaction was monitored by UV absorption spectroscopy.The order of adding raw materials had impact on the size of Cu nanoparticles.Uniform Nano-copper is synthesized easily by dropping mixture of polyvinylpyrrolidone and copper sulfate to hydrazine hydrate.Stable Cu/Ag nanoparticles can be prepared by dropping hydrazine hydrate to mixture of polyvinylpyrrolido... |
