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.

采用化学气相沉积法制备了BC2N和BC6N组成的类石墨层状材料。钠(Na)通过电化学法和气相反应插层到BC_2N中，而Na几乎不插层到石墨中。X-射线吸收光谱表明，BC_2N的一个空的π*轨道具有较强的强度，轨道底部的能量低于石墨、非晶碳和BC_6N的底部。这一结果表明，包括Na在内的碱金属可以比其他主体材料更有效地插层到BC2N中。
