Özet

The main purpose of this paper is binary transition metal oxides NiO-Co3O4 which can provide high capacitance through alternating oxidation and reduction in wide potential range at low cost without any connector, flexible synthesis method, due to well-defined electrochemical behaviors and high theoretical capacity, provide better performance in batteries the future is to produce alternative electrode materials. Double metal oxide NiO-Co3O4 nanoparticles with high capacitance to show the electrodes were synthesized by a new electrochemical method in their application was investigated systematically. In this context, although many methods related to the synthesis of NiO-Co3O4 have been studied extensively, electrochemical methods with parameters that allow for more practical, environmentally friendly, inexpensive and inherently interfacial and size controlled material deposition have not yet been fully investigated. These compound semiconductors can be used at room temperature and atmospheric pressure, without additional steps and no further processing, NiO/Co3O4 nanostructured electrodes, again electrochemically synthesized, were prepared directly on ITO and the desired composition, structure, size, ITO/NiO/Co3O4 were readily synthesized by controlling the electrochemical parameters such as potential and time. The surface morphology of the prepared three dimensional (3D) electrodes, scanning electron microscopy (SEM), the chemical composition of energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) characterization and the crystal structure analysis were made by X-ray diffraction XRD.
