Preparation of Expanded Graphite with Fe₃O₄ Nanoparticles

Abstract:

In this paper, it can be seen that the optimum mixture ratio of graphite to other contents (graphite: H₂SO₄: H₂O₂: HClO₄) is 10(g):28(ml):1(ml):5(ml), which obtained the best expansion volu_{Subscript text}me (191ml/g). The Fe₃O₄-expanded graphite composite material was prepared by FeCl₃ solution of ethylene glycol with heating reaction in reactor. The graphite sheets within EG were nanoscales, four iron oxide nanoparticles were dispersed between holes of expanded graphite sheets. Evidently, the graphite nanosheets wrapped in the four iron oxide particles can be observed. It is clearly that the magnetic adsorption properties of particles are strength on EG/Fe₃O₄. In addition, the EG/Fe₃O₄ composite obtained by this process has a product (magnetite), which is proved of XRD characteristic peaks.
