Abstract

Using hydrophilic nitrogen-doped carbon tubes (N-CTs) as supports, prepared by carbonization of the mixture of lysine and ferric chloride, ultrafine Pt nanoparticles were highly dispersed on the N-CT sidewalls. Electrochemical analyses found that the methanol oxidation activity of the Pt/N-CTs was ∼2.1 times that of a commercial Pt/C catalyst. The improved performance correlated to the high dispersion of ultrafine Pt nanoparticles and the synergistic effect between Pt and the N-CTs.
