Nitrogen-doped graphene (N-graphene) is obtained by exposing graphene to nitrogen plasma.
N-graphene exhibits much higher electrocatalytic activity toward oxygen reduction and H2O2
reduction than graphene, and much higher durability and selectivity than the widely-used expensive Pt
for oxygen reduction. The excellent electrochemical performance of N-graphene is attributed to
nitrogen functional groups and the specific properties of graphene. This indicates that N-graphene is
promising for applications in electrochemical energy devices (fuel cells, metal­air batteries) and
