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.展开更多
