“…Strong acids such as H 2 SO 4 [6] and HNO 3 [7] are known to form graphite intercalation compounds (GICs), which act as precursors for preparing expandable and flexible graphite sealing materials. Recently, the research on expandable graphite with low-sulfur content [8] or no-sulfur [9] has attracted much attention due to erosion and environmental pollution caused by sulfur-containing compounds. The aims of this work were to prepare expanded graphite with larger expansion volume, and it was prepared using natural graphite as raw material.…”

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 voluSubscript textme (191ml/g). The Fe3O4-expanded graphite composite material was prepared by FeCl3solution 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/Fe3O4composite obtained by this process has a product (magnetite), which is proved of XRD characteristic peaks.

In this paper, it can be seen that the optimum mixture ratio of graphite to other contents (graphite: HNO3: H2O2: KMnO4 ) is 1.0(g):6(ml): (2.0ml):(0.2g), which obtained the best expansion volume. The graphite sheets within EG were nanoscales, rare earth nanoparticles were dispersed between holes of expandable graphite sheets. Evidently, the graphite nanosheets wrapped in the rare earth particles can be observed. It is clearly that the rare earth particles within EG were nanoscales. In addition, rare earth particles on expandable graphite were nanoscales, and the EG/CeO2 composite obtained by this process is a product with amorphous alloy structure.
