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