  • Method for producing carbon nanotubes using a DC non-transferred thermal plasma torch
    Patent number: 7846414
    Abstract: The present invention provides a process for the manufacture of carbon nanostructures, the carbon nanostructures being selected from carbon nanotubes and carbon nano-onions. The method comprises the steps of injecting a carbon-containing gas into a plasma flame generated from a plasma forming gas to provide atomic carbon, which in the presence of in situ generated nanometer sized metal catalyst particles that act as nucleation points for growth of carbon nanostructures, produce the carbon nanostructures, and collecting the carbon nanostructures.
    Type: Grant
    Filed: November 17, 2003
    Date of Patent: December 7, 2010
    Assignee: McGill University
