A nitrogen-doped reduced graphite oxide (rGO) has been prepared by high temperature pyrolysis from a Polypyrrole/GO composite yielding high nitrogen content, with specific graphitic and pyridinic bonding as electrochemically active sites for the oxygen reduction reaction. The effect of the N-doped GO supports for CoSe chalcogenide nanoparticles on the electrochemical properties was evaluated in both half-cell, and micro-laminar flow fuel cells (mu LFFC) in alkaline medium. The improved performance toward the oxygen reduction reaction (ORR) can be attributed to the availability of active sites on the N-doped rGO specific morphology, and successful coordination of the nitrogen bonds on the carbon lattice.
