- Abstract
- Surface-modified graphitized carbon black (GCB) was produced through carbonization of polypyrrole (Ppy) on the GCB surface to be used as a catalyst support for Pt nanoparticles in electro-oxidation of methanol. The Ppy modification led to the enhancement of the catalytic activity for the Pt catalysts. The improvement is largely attributed to uniform dispersion of the Pt nanoparticles as the Ppy modification appears to reduce the agglomeration of the Pt nanoparticles. The chronoamperometry and the accelerated cycling tests indicated that the Ppy modification did not improve the long-term stability of the GCB support for Pt. (C) 2011 Elsevier B.V.
