US Patent 8007908 - Single walled carbon nanohorn adsorptive material

Sumio Iijima of NEC is frequently given credit for the discovery and analysis of carbon nanotubes in 1991. More recently Iijima has been studying carbon "nanohorn" material having superior adsorptive properties. This patents teaches a carbon nanohorn material useful for storing methane gas for energy and enviromental applications. Claim 1 reads:

1. A single walled carbon nanohorn adsorptive material having methane absorptivity, wherein a lanthanide metal is deposited on a single walled carbon nanohorn.
