Abstract:
1. A method for fabricating carbon nanotubes, the method comprising: (a) uniformly distributing metallic catalyst particles over a carbon substrate; and (b) supplying a carbon source gas at a constant rate under atmospheric pressure and reacting the carbon source gas with the metallic catalyst particles at a temperature of 400-900° C. for 1-120 minutes, wherein step (b) further comprises adjusting reaction conditions such that a plurality of the growing carbon nanotubes have said metallic catalyst particles adsorbed therein that act as nuclei from which carbon nanotubes branch off and adjusting the reaction conditions comprises supplying a reducing gas after about 10 minutes from beginning the supplying of the carbon source gas.
