A Novel Chemical Reduction Route towards the Synthesis of Nickel Nanoparticles at Room Temperature
Pure metallic nickel nanoparticles, spherical shape have been successfully synthesized by the chemical reduction of nickel chloride with hydrazine at room temperature without any protective agent and inert gas protection. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were employed to characterize the nickel nanoparticles and of course, the magnetic properties were also measured. This synthetic method is proven to be simple and very facile. And it’s very interesting that the obtained nickel nanoparticle can be isolated in solid states and stabilized for several months in atmosphere.
