Abstract:

We prepared a new kind of N-doped amorphous carbon (CxN) by the calcination of poly-o-toluidine (POT) at 800 °C. The prepared CxN consisted of about 8.5% (w) nitrogen. Pd nanoparticles were deposited on CxN because of the inherent chemical activity arising from nitrogen incorporation. The Pd/CxN composite catalyst has a large electrochemically active surface area and it shows good electrocatalytic performance and stability toward methanol oxidation in alkaline media. All the results suggest that CxN can potentially find application in fuel cells.

Key words: Alkaline direct methanol fuel cell, Poly-o-toluidine, Calcination, N-doped amporphous carbon, Pd nanoparticle
