Low-Temperature Growth of Carbon Nanotubes

Multiwalled carbon nanotubes filled with Cu metal, Cu2O, and CuCl are produced by poly(vinyl alcohol) carbonization in the presence of CuCl or CuCl2 . The structure and composition of the reaction products are analyzed by x-ray photoelectron spectroscopy, transmission electron microscopy, and selected-area electron diffraction. The carbonization products are found to contain, along with carbon nanotubes, carbon-encapsulated spherical metallic nanoparticles and carbon fibers. A simplified mechanism of nanotube growth is proposed which differs from the well-known high-temperature mechanism.
