When pure graphite rods are used, fullerenes are deposited as soot inside the chamber, and multi-walled carbon nanotubes are deposited on the cathode. When a graphite anode containing a metal catalyst (Fe or Co) is used with a pure graphite cathode single-walled carbon nanotubes are generated in the form of soot. direct current arc-discharge method arc-evaporation of graphite
