Synthesis and characterization of BIFEO3 Nanoparticles for supercapacitors

Abstract

In the present study, bismuth ferrite (BiFeO₃) nanoparticles were synthesized by a simple and cost-effective co-precipitation method. The synthesized materials were characterized by X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, and Field Emission Scanning Electron Microscopy (FE-SEM) with Energy dispersive X-ray spectrum (EDAX). Finally, the electrochemical performance was analysed using cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) analysis. From the XRD results, it was found that there was a formation of rhombohedral-structured BiFeO_3, and the average crystallite size of BiFeO₃ was calculated to be 14 nm. The FTIR analysis confirmed the existence of possible functional groups such as Bi-O & Fe-O. There was a formation of almost spherical-shaped particles in the size range of 20-40 nm as evident from FE-SEM images. The EDAX spectra of the prepared nanoparticles provided the composition of BiFeO₃. Finally, the electrochemical studies demonstrated that BiFeO₃ could be utilized as a potential electrode material for supercapacitors.
