Pseudocapacitive Behavioral Testing of Iron Vanadate Nanoparticles Synthesized by Simple Co- Precipitation Method

Abstract

Iron vanadate nanoparticles were prepared by simple co-precipitation method. The crystal structure and elemental composition of prepared material were confirmed using X-ray Diffraction analysis and Elemental Dispersive X- ray spectroscopic analysis respectively. Surface morphology of the sample was analyzed by Scanning Electron Microscopic techniques. Optical absorption and molecular vibrations were studied by UV-Vis. absorption spectroscopy and Fourier Transform Infrared spectroscopic techniques. Electrochemical behaviors such as redox property, charge-discharge mechanism and impedance analysis were examined with cyclic voltammetry, Galvanostatic charge-discharge and electrochemical impedance spectroscopic studies.
