| Outline of Final Research Achievements |
By controlling the energy difference between the highest occupied defect level of the doped atoms and the bottom of the conduction band of h-BN, the catalytic activity and active area of surface can be tuned. In the present research, the system closed to the experimental ones with multiple carbon atoms was investigated. The influence of, concentration, edge effect, the geometry of doped carbon atoms on the electronic properties and the stability of C@h-BN surface was clarified. The catalytic activity of C@h-BN surface for O2 molecule activation can be predicted by the electronic structure of the surface. The computational time is high decreased. The C@h-BN surface with high catalytic activity of O2 molecule activation was proposed theoretically.
