It is found that the nanotubes are frequently coated with a disordered carbon, and that the tubes are often incompletely formed, with nanohorn-like structures attached to the caps. This suggests that carbon nanohorns may be the precursors for the formation of nanotubes by arc-discharge. A possible mechanism for this process is suggested.
