摘要： The present invention relates to a method for preparing a carbon nanotube-producing catalyst using chemical vapor deposition method. Using the above preparation method, a uniform and thin coating layer can be formed even on the surface of a support having a high-specific-surface-area having a 3D structure, and high-quality and low-diameter carbon nanotubes can be produced using the catalyst prepared through this method.
