Electrochemical behaviour of flower Like NiCO₂O₄ nanostructures in different electrolytic systems

Here, NiCO₂O₄ nanostructures have been prepared by hydrothermal method for their application as electrode material in supercapacitors. The prepared material is characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Visible spectroscopy and Field effect scanning electron microscopy (FESEM). XRD analysis reveals the successful synthesis of spinel cubic phase of nickel cobalt oxide nanostructures and the crystallite size corresponding to various planes has been calculated. In FTIR spectrum, the presence of metaloxygen bond confirms the formation of the desired nanostructures. The FESEM images shows the formation of highly porous hollow nanostructures of NiCO₂O₄ which are the suitable structures to provide more electro active sites for electrolyte ion penetration and redox reactions to occur
