Abstract
The three different ratios of NiCo2O4 nanostructures have been synthesized using nickel nitrate hexa hydrate, cobalt nitrate hexa hydrate and potassium hydroxide via co-precipitation method and their morphological, optical and electrochemical properties is proposed. Room temperature (RT) photoluminescence investigation reveals near band emission (NBE) in all samples. Then the synthesized NiCo2O4 nanostructures were utilized to modify the glassy carbon electrode (GCE) for electrochemical characterization. The cyclic voltammetry test of the 1:1, 1:2 and 1:5 NiCo2O4 modified glassy carbon electrodes (NiCo2O4/GCE) shows without any redox peaks on both anodic and cathodic sweeps, which indicates the ideal capacitive behavior and the corresponding specific capacitance are 753, 788 and 574 Fg−1 respectively at 5 mV s−1. The cost effective NiCo2O4 nanostructures are suitable for the applications in optoelectronic and energy storage devices.
