Abstract
Provided is a method for synthesizing cobalt-incorporated carbon nanotubes (Co/MWCNTs). The method includes a step of mixing cobalt acetate, cobalt nitrate, cobalt chloride, or cobalt sulfate with multi-wall carbon nanotubes in a solvent. A method for generating hydrogen by using the Co/MWCNTs as a catalyst component is also provided herein.
Claims17
A method for making a carbon nanotube-based catalyst, comprising:
- mixing cobalt acetate with multi-wall carbon nanotubes (MWCNTs) in a solvent to produce a solution, wherein the MWCNTs comprise nested single-wall carbon nanotubes at a purity of > 99%;
- drying the solution at 70-95° C. to form a powder;
- and
- annealing the powder at 400-600° C. to produce cobalt-incorporated multi-wall carbon nanotubes (Co/MWCNTs).
