Abstract

In this paper, we present the synthesis of Ni nanoparticles supported on graphene (Ni/G) using graphene oxide (GO) and Ni2+ ions as starting materials. GO is mixed with NiCl2 solution and treated by hydrazine. Hydrazine both reduces the GO and forms a complex with nickel(II). A treatment in the tubular furnace allows decomposing the nickel-hydrazine complex into Ni metallic nanoparticles as well as further reducing the GO into graphene. The materials are characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy and thermogravimetrymass spectrometry as well as tested for methanol electrooxidation in alkaline medium.
