Method for preparing catalyst supports and supported catalysts from single walled carbon nanotub |
July 8, 2008 |
| A new method for preparing a supported catalyst is herein provided. A carbon nanotube structure such as a rigid porous structure is formed from single walled carbon nanotubes. A metal catalyst is then loaded or deposited onto the carbon nanotube structure. The loaded carbon nanotube |
