Abstract (EN): A highly efficient process was developed to synthesize one dimensional (1D) array of Ni(OH)(2) on Ni/RGO nanocomposite by a two step method. In the first step, Ni nanoparticles (NPs) were decorated on reduced graphene oxide (RGO) by the simultaneous reduction of Ni2+ ions and graphene oxide (GO) under reduced conditions. In the next step, one dimension (1D) arrays of Ni(OH)(2) were uniformly grown on Ni/RGO by the precipitation of Ni2+ ions using urea and NaOH. The reduction of GO, formation of Ni/RGO and Ni(OH)(2)@Ni/RGO nanocomposite were verified by various techniques. The magnetic hysteresis loop of as-synthesized nanocomposite Ni(OH)(2)@ Ni/RGO exhibits the typical ferromagnetic properties with a saturation magnetization of 4.8 emu/g, which holds a broad prospect of 1D array on graphene for many applications.
