Author(s): E Chinnasamy, K Balamurugan
Abstract: In the present work demonstrates a sol-gel approach for the preparation of nanosized ZnO for use in supercapacitor applications. For that zinc acetate dihydrate and sodium hydroxide have been utilized in the presence of solvent medium bunker C fuel oil. The preparation of ZnO NPs was analyzed for their structural, morphological and electrochemical properties. The results of X-ray diffraction imply that the prepared particles are having hexagonal wurtzite structure with average crystallite size of the ZnO NPs are 19 nm. SEM micrograph of ZnO NPs was observed by spherical like morphology. The cyclic voltammetry of ZnO NPs provides the peaks of oxidation and reduction revealing its supercapacitor nature. Furthermore, at a scan rate of 10 mV/s, ZnO exhibited a capacitance of 396 F/g for supercapacitor application.
