Synthesis and physicochemical characterization of V2O5/g-C3N4 composites as an electrode material in supercapacitors

Abstract

The main goal of this thesis is to ascertain, if the prepared composite material (V2O5/g-C3N4) is suitable for supercapacitor electrodes. The theoretical part describes elementary properties of the used materials as well as the chosen method for the fabrication of the composite. Next it deals with the description of analytical methods used for its characterization. Further it describes supercapacitor properties and their types as well as their comparison to batteries. The experimental part includes the lists of used chemicals and laboratory equipment, the preparation of the samples as well as the supercapacitor cell assembly process. Lastly it presents the achieved results in structural, morphological, and electrochemical order to best describe the issue.
