Abstract Scope |
In the present work, we creatively synthesized a three-dimensional reduced graphene-oxide based Ni(OH)2/RGO core-shell structure using a very simple and low-cost process, followed by its dip coating on the Ni foam. The core-shell nanostructure was composed of Ni(OH)2 nanosphere at the core and RGO layers as shells. Synthesized Ni(OH)2 nanospheres were characterized by x-ray diffraction for crystal structure analysis. Core-shell morphology of Ni(OH)2/RGO hybrid was confirmed by transmission electron microscope. Presence of RGO in Ni(OH)2/RGO hybrid was confirmed by x-ray photon spectroscopy. The as-prepared Ni(OH)2/RGO hybrid was used as supercapacitor electrode for electrochemical measurements. Effect of annealing temperature on electrochemical properties of prepared electrode was also studied. Results of present study indicate that the Ni(OH)2/RGO core-shell hybrid can be a potential electrode material for supercapacitors. |
