In this work, nickel-cobalt binary oxide (Ni2CoO4) nanomaterials were synthesized through a facial hydrothermal method using cobalt nitrate, nickel nitrate and trimethylamine as surfactants. The synthesized Ni2CoO4 was applied as electro-active electrode material for the fabrication of electrochemical supercapacitor. From the morphological characterizations, porous hexagonal discs (HDs) like nanostructures, comprised of stacked layers with the average diameter of ~500 nm were confirmed. The synthesized Ni2CoO4 HDs displayed a high surface area of ~ 78.69 m2/g with good pore size distribution and pore volume. The charge storage ability, cycle stability and ion transport of the synthesized Ni2CoO4 HDs electrode were investigated by performing cyclic voltammetry (CV) in 6 M KOH electrolyte. |
