Abstract
The present invention provides a combustion-based method and apparatus for producing and isolating carbon nanotubes. The nanotubes are formed when hot combustion gases are contacted with a catalytic surface, which is readily separated from the catalyst support and subsequently dissolved. The process is suitable for large-scale manufacture of carbon nanotubes.
