Materials were annealed at various temperatures between 100 degrees C-600 degrees C. The morphological properties of the synthesized material were studied by transmission electron microscopy. The surface area for sample annealed at 360 degrees C was determined to be 85.64 m(2)/g using Brunauer-Emmett-Teller method. The nitrogen adsorption and desorption isotherm displayed a typical type-IV isotherm. Electrochemical properties of produced material were studied using cyclic voltammetry, long term charge/discharge analysis and impedance spectroscopy in the 0.5 M Na2SO4 electrolyte. The obtained nanostructured porous electrode exhibits quasi-rectangular shaped cyclic voltammetry curves with a specific capacitance of 2190 F/g at a scan rate of 2 mV/s.eninfo:eu-repo/semantics/openAccessSupercapacitorsOxideConference Object131345345610.12693/APhysPolA.131.4532-s2.0-85018712141Q4WOS:000400905500033Q3
