Graphite Fluoride Intercalation Compounds for Manufacturing Composites with Metal Nanoparticles

摘要

The feasibility of using graphite fluoride intercalation compounds (GFICs) containing metal compounds for manufacturing metal nanoparticles in a graphite or graphite fluoride matrix is shown using the hydrogen reduction of a dicarbon fluoride matrix intercalated with a chloroform solution of palladium acetyl-acetonate Pd(AA)2. The composite manufactured with a GFIC containing about 10.5 wt percent Pd(AA)2 at 80 deg C is Pd-fluorographite; at 450 deg C, Pd-graphite is manufactured. The palladium particle size in the composites is about 20-30 nm; the palladium concentration is about 5 and 9 wt percent, respectively.
