Abstract
A new method for preparing a supported catalyst is herein provided. The supported catalyst comprises a carbon nanotube network structure containing metal catalysts. The metal catalyst may be loaded onto functionalized carbon nanotubes before forming the carbon nanotube network structure. Alternatively, the metal catalyst may be loaded onto the carbon nanotube network structures themselves.
