Intercalation of sodium into graphite-like layered material BC2N

Abstract

Graphite-like layered material of composition BC2N was prepared by the CVD reaction of acetonitrile with boron trichloride at 2070 K. Sodium was intercalated into the BC2N film and powder by two methods: a vapor phase reaction and an electrochemical method. The first stage compounds were prepared by the vapor phase reaction using the BC2N film and powder. A mixture of the first and the second stage compounds was prepared from the BC2N powder, while the first stage compound was prepared from the BC2N film by the electrochemical method. The d-spacing of the intercalated layers was 0.43 nm, calculated from the sharp (001) and (002) diffraction lines observed on the X-ray diffraction patterns of the first stage compounds prepared from the BC2N films by the two methods.
