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.

Simultaneous nitrogen doping and reduction of graphene oxide.

The N-doped reduced GO shows clearly n-type electron doping behavior with the Dirac point (DP) at negative gate voltages in three terminal devices, and electrical measurements of individual GO sheet devices demonstrate that GO anneal in NH(3) exhibits higher conductivity than those annealed in H(2), suggesting more effective reduction of GO by annealing in NH-3 than in H-2, consistent with XPS data.
