1. A method for producing single walled carbon nanotubes comprising:

  • (a) reacting a carbon containing gas under reaction conditions with a composition comprisingfullerene on a precursor of a metal catalyst, wherein the precursor of a metal catalyst is coated with a thin film of fullerene, andwherein said reaction conditions are suitable for reducing said metal catalyst precursor, said conditions being at atmospheric pressure or greater; and

    (b) growing single walled carbon nanotubes, wherein said fullerene serves as a seed for growth of the single walled carbon nanotubes.
