Characterization and Application of Expanded Graphite Coated by Fe3O4 Nanoparticles
The expanded graphite coated with different portions of Fe3O4 nanoparticles (EG/ Fe3O4) were synthesized by a simple hydrothermal reaction and the composite was characterized by scanning electron micrograph (SEM), X-ray diffraction (XRD) and infrared spectroscopy (IR). The catalytic performance of the composite was studied through the degradation of methylene blue. The results indicated that a complete and uniform Fe3O4 nanoparticles coating on expanded graphite could be obtained under routine pressure and temperature and the optimum content of Fe3O4 in the composite was 6wt% in the experiment of catalytic degradation of methylene blue.
