- Abstract
Mesoporous NiCo2O4 nanocomposites have been successfully synthetized by a xerogel route followed by heat-treatment process using propylene oxide as a gelation agent. The prepared materials are characterized by X-ray diffraction, FESEM, HRTEM and N2 adsorption/desorption. The results suggest the NiCo2O4 nanocomposites possessing a high specific surface area of 134 m2 g 1 and a mesoporous structure. Cyclic voltammetry (CV) and galvanostatic technique are employed to evaluate the mesoporous NiCo2O4 electrode in 7 M KOH aqueous solution. A maximum specific capacity of 392 C g 1 is calculated on the basis of the galvanostatic discharge curve at a current density of 1 A g 1, implying excellent performance for a battery-type electrode.
