Abstract

Reduced graphene oxide (rGO)–Fe?O? nanocomposites have attracted considerable attention due to their unique combination of electrical conductivity, large surface area, and magnetic properties. In the present study, rGO– Fe?O? nanocomposites were synthesized through a simple chemical reduction and reflux-assisted approach. Reduced graphene oxide was prepared from graphene oxide using hydrazine hydrate as a reducing agent, while Fe?O? nanoparticles were synthesized using ferric chloride, ferrous sulfate, and urea. The prepared Fe?O? nanoparticles were subsequently incorporated onto rGO sheets to obtain the nanocomposite. Structural characterization was carried out using Fourier Transform Infrared (FT-IR) spectroscopy and X-ray Diffraction (XRD) analysis. FT-IR spectra confirmed the presence of Fe–O stretching vibrations characteristic of magnetite and indicated successful interaction between rGO and Fe?O? nanoparticles. XRD patterns revealed the crystalline spinel structure of Fe?O? and the characteristic diffraction peak of reduced graphene oxide, confirming successful nanocomposite formation. The results demonstrate that Fe?O? nanoparticles were effectively anchored onto rGO sheets, resulting in improved structural stability and potential applicability in environmental catalysis, energy storage, and sensing applications.
