ABSTRACT
The electrochemical performance of zinc cobaltite–based nano/micromaterial depends on its shape and morphology. Here we report on the electrochemical performance of zinc cobaltite (ZnCo O ) material synthesized via a facile 2 4 hydrothermal method. The synthesized material was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) analysis. It was found to be a single-phase zinc cobaltite material with a cubic spinel crystal structure. The electrochemical performance of the synthesized zinc cobaltite microstructure material was evaluated by cyclic voltammetry, cyclic chronopotentiometry and electrochemical impedance -1 -1 spectroscopy. The zinc cobaltite microspheres material displayed a high specific capacitance of 600.37 F g at a current density of 1 A g . Such electrochemical performance may qualify the zinc cobaltite microspheres material as a potential electroactive material in supercapacitors.
