| Research Abstract |
Graphite-like layered material of compositions BC_2N and BC_6N were prepared by chemical vapor deposition method. Sodium (Na) was intercalated into BC_2N by the electrochemical method as well as the vapor phase reaction, while Na was hardly intercalated into graphite. X-ray absorption spectroscopy indicated that an unoccupied π* orbital of BC_2N showed relatively strong intensity and a bottom of the orbital was at an energy lower than each bottom of graphite, non-crystalline carbon and BC_6N. This result suggests that alkali metals including Na can be intercalated into BC_2N more effectively than the other host materials.
