Exploration of the active center structure of nitrogen-doped graphene-based catalysts for oxygen reduction reaction

Short summary

Nitrogen-doped graphene (N-graphene) fabricated via annealing graphene oxide with ammonia or polymer/reduced graphene oxide composites acts as an effective metal-free catalyst for the oxygen reduction reaction (ORR), with graphitic N content determining limiting current density and pyridinic N content improving onset potential.
