Abstract

original image

PANI-based carbon cat: A low-cost nitrogen-doped carbon nanomaterial from polyaniline as fuel cell cathode electrocatalyst is prepared by chemical polymerization of aniline monomers, followed by pyrolysis in the presence of ammonia. The catalyst demonstrates high activity, with an onset potential comparable to, and a reduction current higher than, a commercial platinum catalyst.
