    Project supported by the National Natural Science Foundation of China (No. 21071122) and Research Fund for the Doctoral Program of Higher Education of China ( No. 20091333110009) and the Outstanding Youth Fund of Hebei Province (No. E2010001169).

A solvothermal method has successfully applied to prepare hexagonal boron carbonitride from CH3CN, NaN3 and NaBF4 in benzene at 400 ℃. The synthesized product was characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), select area electron diffraction (SAED), X-ray energy-dispersive spectroscopy (EDS), and electron energy loss spectroscopy (EELS). XRD and SAED indicated that the synthesized product are h-BCN with the lattice constants of a=0.2678 nm and c=0.6639 nm. TEM images reveal that the products mainly consist of nanorods and quartet prism-like nanostructure. The results of EELS and EDS suggested that the product was composed of elements of B, C and N, and the chemical formula was B0.23C0.60N0.17. FTIR exhibited that the product had C—N, B—C and B—N bonds, indicating that an atomic-level hybrid of the three elements was synthesized.

Key words: boron carbonitride, solvothermal synthesis, transmission electron microscopy
