| Outline of Final Research Achievements |
In this study, hetero atom doping of graphene was investigated. Doping was carried out by neutral beam process that enables to irradiate energy-controlled beam. In the case of nitrogen doping in graphene, it is found that the formation of nitrogen-carbon bond depends on energy of irradiated beam, thus CN double bond (pyridinic nitrogen) is formed under higher energy (12 eV) and CN single bond (graphitic nitrogen) is formed under 7 eV. Furthermore, nitrogen doped graphene shows catalytic activity of oxygen reduction reaction, and graphitic nitrogen has higher activity.
