US Patent 7816709 - Single walled CNT-ceramic composites

This patent out of the University of Oklahoma is based on the finding that using a ceramic (e.g. silica) support can increase the quality of single walled carbon nanotubes. Claim 1 reads:

1. A nanotube-polymer composite comprising:

a polymer; and

a carbon nanotube-ceramic composite, including:

a metallic catalytic particle, having:

at least Co, Mo, and a support material, combined to have a particulate form; and a carbon product deposited on the metallic catalytic particle, at least 80% of the carbon product comprising single-walled carbon nanotubes.
