US Patent 7744843 - Bulk synthesis of CNTs
http://www.freepatentsonline.com/7744843.html
This patent from Drexel University teaches a way of using chlorine gas to facilitate the mass production of single walled carbon nanotubes. Claim 5 reads:
5. A method for synthesizing carbon nanotubes, comprising:
extracting metal from a carbide substrate using one or more halogens at a temperature in the range of from about 700 C. to about 2000 C.; and
growing carbon nanotubes in a non-vacuum pressure environment on the substrate upon conversion of the carbide substrate into carbon.
