Electrocatalytic oxygen reduction on nitrogen-doped graphene in alkaline media

- Pyrolysis in the presence of nitrogen precursors was used for N-doping of graphene.
- Melamine, urea and dicyandiamide were pyrolysed with graphene oxide at 800 °C.
- N-doped graphene nanosheets were used as catalysts for oxygen reduction reaction.
- N-doped graphene showed a high electrocatalytic activity for ORR in alkaline media.
- N-containing graphene is a promising cathode catalyst for alkaline membrane fuel cells.
