Abstract
Apparatus () for producing a multi-wall carbon nanotube () may comprise a process chamber (), a furnace () operatively associated with the process chamber (), and at least one filament () positioned within the process chamber (). At least one power supply () operatively associated with the at least one filament () heats the at least one filament () to a process temperature. A gaseous carbon precursor material () operatively associated with the process chamber () provides carbon for forming the multi-wall carbon nanotube (). A metal catalyst material () operatively associated with the process () catalyzes the formation of the multi-wall carbon nanotube ().
