摘要

Carbon nitride nanobelts and nanotubes were synthesized through polycondensation of dicyandiamide (H4C2N4) and melamine (C3N6H6) at 290 degrees C and 4.5-5 MPa. The as-synthesized samples were investigated by powder x-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, elemental analysis and photoluminescence spectra. The results indicate that a new kind of graphite-like carbon nitride nanobelt and nanotube has been synthesized. The widths of the nanobelts range from 100 nm to 3 mu m, the thickness is about 5-50 nm, and lengths range from several micrometres to tens of micrometres or longer. The nanotubes have outer diameters of 70-200 nm, inner diameters of 5-20 nm, and lengths of several micrometres. These nanobelts and nanotubes have luminescent properties and may have potential uses as components of optical nanoscale devices. The mechanism of formation is also investigated.
