Abstract Submitted to the ; NANOTUBE'05 Conference:

A novel coral-like carbon nanotubes was presented in this paper. They were prepared by a modified arc discharging furnace[1] in hydrogen atmosphere with a mixture of Mo-Co2O3-Mg powders as catalyst at 600℃. This carbon nanotubes presents a microscopic coral-like by a SEM and a TEM observation, and amorphous carbon nanotubes by a HRTEM observation. But the XRD diffraction pattern presents a crystal characteristics compared with normal graphite structure. It is very strange that the results are uniform. We think that these results may be affected by catalyst, atmosphere and temperature. Tried explanations to the formation mechanism of this novel carbon nanotubes have also been proposed.
