Preparation and Structure of CeO<,2>-Graphite Intercalation Compounds
Rare-earth oxide graphite intercalation compounds (CeO<,2>-GICs) were prepared using graphite and CeO <,2> as raw materials by vacuum heat-treatment. The stage-5 GICs was formed after heat treatment at 800℃, and it was examined and characterized by X-ray diffraction (XRD). The XRD analysis of intercalation compounds indicated that a number of noncarbon reactant (atom, molecule, ion or groups) could intercalate the layers of graphite with reticulated layer structure physically. Consequently the layered structure of graphite changed and new physical and chemical properties were obtained. X-ray photoelectron spectroscopy (XPS) suggested that the compound intercalated into graphite should contain Ce <Ⅳ> compounds.
