【 摘 要 】

The preparation of amine-modified iron oxide/carbon (Fe3O4/C) nanoparticles was performed by the submerged arc discharge method using graphite electrodes and a liquid medium consisting of 50% ethanol and added ethylenediamine. The arc discharge was conducted by passing a voltage of 20-40 V. Two graphite electrodes were used, where one of them was filled with Fe3O4, carbon graphite and binder in a mass ratio of 1:3:1. The properties of the fabricated Fe3O4/C nanoparticles were analysed using X-Ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The XRD diffractogram pattern of the prepared Fe3O4/C showed definitive peaks at 26.5238° and 35.6374°, which are the main characteristic peaks of C graphite and Fe3O4, respectively. SEM analysis showed that the nanocomposite had a spherical morphology. TEM analysis found that the structure of the nanocomposite was Fe3O4-coated carbon.
