US Patent 7799726 - CNT composites

This patent has relatively early priority (2001) and includes some broad claims toward catalysts supports including a large weight fraction of carbon nanotubes or nanofibers. Claim 1 reads:

1. A composite consisting essentially of:

an impregnated support activated by impregnation of at least one metal and/or metal salt and carbon nanotubes or nanofibers formed by vapor deposition, wherein the weight of said carbon nanotubes or nanofibers formed on said support is at least 10% of the weight of said composite.
