METHOD FOR PREPARING METAL CATALYST FOR PREPARING CARBON NANOTUBES AND METHOD FOR PREPARING CARBON NANOTUBES USING THE SAME

摘要

A method of preparing a metal catalyst for preparing carbon nanotubes and a method of preparing carbon nanotubes using same. In one embodiment, a deposition-precipitation method is used. The method includes preparing a support dispersion solution in which a solid support is dispersed in a solvent; and injecting a metal precursor salt solution and a pH adjusting solution into the dispersion solution to prepare a mixed solution and adsorbing metal oxides or metal hydroxides formed therefrom on a surface of the solid support to prepare a catalyst particle.
