Abstract:
Herein, we offer the study on the conductive polymer of polypyrrole and iron oxide (Fe 2 O 3 @PPy) nanocomposites, which are prepared via a simple chemical oxidation method for energy storage applications. The synthesized nanocomposites are confirmed by the physico-chemical properties through Fourier Transform Infra-red Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and X-ray Photoelectron Spectroscopy (XPS) results along with Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry (CV), Galvanostatic Charge–Discharge (GCD) and stability analyses. The surface morphological studies of SEM and high TEM images substantiated the formation of Fe 2 O 3 @PPy nanocomposite via the polymerization process. The prepared Fe 2 O 3 @PPy nanocomposites deliver at a specific capacity of 395.45 C g −1 at 5 mV s −1 scan rate. Moreover, Fe 2 O 3 @PPy nanocomposite shows outstanding cycling stability of capacity 94.3% even after 10000 cycles of charge-discharge at the highest current density value of 10 A g −1 . The remarkable electrochemical energy storage manner of as-synthesized Fe 2 O 3 @PPy nanocomposite is considered a potential electrode for supercapacitor application. The higher electrochemical performance of this Fe 2 O 3 @PPy nanocomposite it’s suitable for numerous applications like batteries, sensors, photocatalysts, solar cells and commercial requirements.
