| Outline of Final Research Achievements |
Exfoliated carbon fibers, ExCFs, obtained from the oxidation of carbon fibers contains lots of functional oxygen groups such as -OH and -COOH. Herein we synthesize the two kinds of dendrons; PAMAM and DPA; embedded on ExCFs on which enclosed subnano sized Pt(0) clusters are included. The PAMAM-dendron@ExCFs shows less thermal stability compare to the DPA@ExCFs in TA analysis. The Pt(0) clusters on the ExCFs were prepared by complexation with Pt ions followed by the reduction with NaBH4. We are evaluating the [Pt@Dendron]@ExCFs as an oxygen electrode of a fuel cell.
