摘　　要：A solvothermal reaction of anhydrous C3N3Cl3 and sodium using cyclohexane as solvent and NiCl2 as cata- lyst precursor has been carried out to prepare carbon nitride nanotubes successfully at 230℃ and 1.8 MPa. The carbon nitride nanotubes were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), electron diffraction (ED), elec- tron energy loss spectrum (EELS) and Raman spectrum. SEM and TEM results indicated that the tubes have a length of 20–30 μm, a uniform outer diameter of about 50–60 nm, an inner diameter of 30–40 nm and are highly ordered as- sembled as bundles. The EELS measurement indicated that the ratio of N/C was about 1.00. The ED and XRD analyses revealed that the tube may have a new CN crystalline struc- ture. The growth mechanism of nanotubes was discussed.A solvothermal reaction of anhydrous C_3N_3Cl_23 and sodium using cyclohexaneas solvent and NiCl_2 as catalyst precursor has been carried out to prepare carbon nitridenanotubes successfully at 230 deg C and 1.8 MPa.
