title: N-Doping of graphene oxide at low temperature for the oxygen reduction reaction.
abstract: Nitrogen doping of graphene oxide was demonstrated for the first time at a temperature as low as 5 °C in ammonia solution with the aid of ultrasonication. Controlling the ultrasonication time and bath temperature permitted tuning of the N doping level. The resulting N doped graphene oxide showed high activity towards the oxygen reduction reaction.
