NOVELTY - Preparing carbon nanotube catalyst involves mixing the active component solution, the inactive component solution and the carbon carrier to obtain the precursor solution, and removing the solvent contained in the precursor solution to obtain a precursor. The precursor is calcined under anaerobic conditions to obtain a carbon nanotube catalyst. USE - Method for preparing carbon nanotube catalyst for carbon nanotube (Claimed). ADVANTAGE - The prepared carbon nanotube catalyst improves the yield of carbon nanotubes and reduce the production cost of carbon nanotubes. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing a carbon nanotube catalyst, which involves mixing the active component solution, the inactive component solution and the carbon carrier to obtain a premixed solution, and adding the premixed solution to the carbon carrier to obtain a precursor solution; (2) a carbon nanotube catalyst, which comprises a carbon support and a metal oxide distributed in the carbon support; and (3) a method for preparing carbon nanotubes, which involves using a carbon nanotube catalyst as a catalyst to prepare carbon nanotubes by a vapor deposition method.
