Abstract
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 is preferably ground to powder form.
Claims4
A method of preparing a rigid porous carbon structure having a surface area greater than at least 800 m2/gm, comprising the steps of:
- (a) dispersing a plurality of single walled carbon nanotubes in the form of aggregate particles in a medium to form a suspension;
- said medium including a dispersant selected from the group consisting of alcohols, DNA, glycerin, surfactants, polyethylene glycol, polyethylene imines and polypropylene glycol,
- (b) sonicating said suspension to disaggregate said aggregate particles into a plurality of individual single walled carbon nanotubes,
- (c) mixing said suspension with a gluing agent,
- (d) extruding said suspension and calcining to form said rigid structure of intertwined single walled carbon nanotubes bonded at the nanotubes intersections within the structure.
