AP01058 Graphene Reinforced BFO: New Nanocomposite for Multifunctional Applications for Future Technology

Abstract

This research illustrated the effective synthesis of graphene (0.04 mol) reinforced BFO composite and assessed its spectroscopic properties for various important applications, including supercapacitors and photocatalytic activities. The Raman analysis revealed the presence of D, G, and 2D peaks in the graphene. The energy band gap was measured to be an impressive 1.61 eV. Functional groups associated with the graphene were identified through Fourier-transform infrared (FTIR) analysis. These characteristics, along with the results from transmission electron microscope (TEM) microstructural analysis, confirm the high quality of the few-layer (2-4) graphene. Graphene reinforcement significantly increases the BET surface area of BFO from 4.2 to 78 m²/g. Remarkably, it also reduces the energy band gap of BFO from 2.62 to 1.68 eV upon adding graphene. The electrical conductivity of BFO has been evaluated at 4.2x10^-4 S/cm. However, the conductivity value is projected to increase to 2.58 S/cm for our BFO/graphene (4 mol) composite.
