    摘要: Methods of preparing single walled carbon nanotubes are provided. Carbon containing gas is contacted with a supported metal catalyst under reaction conditions to yield at least 90% single walled carbon nanotubes and at least 1 gram single walled carbon nanotubes/gram metal catalyst. The support material may be calcined at temperatures between 150 and 600° C., and may have at least one oxidized planar surface. Reaction conditions include less than 10 atmospheres pressure and less than 800° C.

    摘要: A new method for recovering a catalytic metal and carbon nanotubes from a supported catalyst is provided. The carbon nanotube, including carbon nanotube structures, may serve as the support for the catalytic metal. The valence state of the catalytic metal, if not already in the positive state, is raised to a positive state by contacting the supported catalyst with a mild oxidizing agent under conditions which does not destroy the carbon nanotube. The supported catalyst is simultaneously or subsequently contacted with an acid solution to dissolve the catalytic metal without dissolving the carbon nanotube.
