HOT WIRE PRODUCTION OF SINGLE-WALL CARBON NANOTUBES

摘要

Apparatus (1) for producing a single wall carbon nanotube (12) may comprise a process chamber (16) and a hot wire (18) positioned within the process chamber (16). A power supply (20) operatively associated with the hot wire (18) heats the hot wire (18) to a process temperature. A gaseous carbon precursor material (14) operatively associated with the process chamber (16) provides carbon for forming the carbon nanotube (12). A metal catalyst material (24) contained within the process chamber (16) catalyzes the formation of the carbon nanotube (12). A process enhancement gas (22), such as hydrogen, may be employed.
