Abstract
A new method for preparing a supported catalyst is herein provided. Carbon nanotubes are functionalized by contacting them with an oxidizing agent to form functionalized carbon nanotubes. A metal catalyst is then loaded or deposited onto the functionalized carbon nanotubes. The mixture is then extruded to form the supported catalyst comprising a carbon nanotube structure containing metal catalyst more evenly dispersed within the internal structure of the carbon nanotube structure.
