Preparation of Platinum-Ruthenium Nanoparticles on Graphite Nanofibers
Electroactivity of graphite nanofibers (GNFs)-supported PtRu particles was examined for their application as DMFCs anode. In this work, composites of PtRu nanoparticles of 2-8 nm size and graphite nanofibers were prepared by the electrodeposition methods. As a result, the methanol oxidation current for graphite nanofibers-supported PtRu catalysts was investigated by changing a deposition time. The electroactivity could be attributed to the particle size, particle dispersion ability, and deposition level.
