In present study, a composite material was synthesized from expanded graphite (EG) and nickel ferrite (NiFe2O4) via the sol-gel method.The composite was then structurally and morphologically characterized which confirmed that NiFe2O4 is successfully incorporated in theexpanded graphite matrix after impregnation. For component characterization, energy diffraction scattering was used. X-ray diffraction(XRD) was employed to determine the physical structure of the nanocomposites. Lastly, pore size structure of EG@NiFe2O was examinedvia the nitrogen adsorption/desorption isotherm and pore size distribution plot.
