Synthesis and characterization of magnetite-graphene oxide nanocomposite

Abstract

This work presents the advances in the synthesis and characterization of magnetite-graphene oxide nanocomposite synthetized by coprecipitation. Structural and physicochemical properties were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). XRD and FT-IR analyses corroborated that magnetite was obtained. Nanoparticle mean size from XRD analysis revealed that it decreased when graphene oxide (GO) was present. TEM displayed that magnetite decorates the GO and VSM revealed superparamagnetic behavior.
