Optical and Electrochemical Properties of Nio Doped Pirlindole(Pin)

Abstract

                The characterization of PIN/NiO nanocomposites are the main topics of this investigation. By using ferric chloride oxidant in the chemical Oxidative polymerization process, polyindole/Nickle oxide was produced. Electrochemical impedance, cyclic voltammetric investigations, Fourier transform infrared spectroscopy, and ultraviolet visible spectroscopy were also used to characterize the produced nanoparticles. Using UV-vis spectroscopy, the intricate optical characteristics of the generated samples were investigated. The polymeric samples as produced showed absorption at wavelengths between 220 and 300 nm. Following Nickle Oxide doping, the optical band gap was found to vary above 4.4 eV to 2.7eV. It is clear that the dopant increases conductivity since the UV-vis spectrum shows that the band gap of the doped PIN decreases. FTIR Spectroscopy was used to examine the surface binding of functional compounds on nanocomposite. In order to better understand the frequency response characteristics of the nanocomposites as the material of electrodes for electrochemical supercapacitors, electrochemical impedance spectroscopy (EIS) studies were performed. Lastly, the cyclic voltammetry (CV) method was used to examine the electrochemical behavior.
