Abstract:
1. A catalyst for manufacturing a carbon nanotube, which is used at the time when the carbon nanotube is manufactured by chemical vapor deposition method in which an atomized carbon-containing raw material is used, which is formed by self-organization of a surfactant in an organic solvent, wherein the catalyst comprises a nanocapsule-type structure having an average particle diameter of 1 to 50 nm, said nanocapsule-type structure comprising an aqueous solution of a metal compound encapsulated in the inside thereof, wherein the surfactant is at least one member selected from the group consisting of an anionic surfactant, dimethyl dialkyl ammonium halide, and a nonionic surfactant, and wherein the dimethyl dialkyl ammonium halide is dimethyl dioctyl ammonium halide.
