Research Abstract |
Exfoliated graphite has very large sorption capacity for oils. Utilizing this property, various metal complexes, silicone compounds, metal alkoxides and others were impregnated into exfoliated graphite, and pretreated, mainly by heat treatment in air or hydrolysis in water vapor, to form precursors. By heating these precursors in an inert atmosphere, the following multi-functional carbonaceous materials were synthesized. (1) Ni/graphite composite, Fe/graphite composite, Fe_3O_4/graphite composite (potential applications : magnetic materials, absorber for electromagnetic radiation, catalyst, and so on) (2) Graphite coated with ultra thin Si-C-O composites (oxidation resistant carbon material, conductive materials at high temperatures) (3) Mn2O3 or MnO2/graphite composite (electrode materials for super capacitors) (4) Nano-particles of single or multi-component metal carbides, such as β-SiC, TiC, ZrC, (Ti,Zr)C and others. The developed method to synthesize (4) is promising as an industrial process because it is simple and low cost.
