Abstract:
1. A method for manufacturing carbon nanotubes comprising the steps of: preparing a metal complex which contains at least one metal selected from a group consisting of iron, cobalt and nickel and an organic compound; and forming carbon nanotubes which contain metal therein by using the organic compound as a carbon source, wherein the carbon nanotubes are formed by putting the metal complex into a heating vessel which has a substance capable of converting electromagnetic energy into heat, and by heating the metal complex using heat which is generated by the heating vessel when electromagnetic energy is applied to the heating vessel; wherein the method further comprises a step of placing the metal complex in the heating vessel between the step of preparing metal complex and the step of forming carbon nanotubes; wherein in the step of placing the metal complex in the heating vessel, the metal complex is placed in the heating vessel by putting the metal complex into a reaction vessel and then placing the reaction vessel in the heating vessel; and wherein the reaction vessel is a crucible and, in the step of placing the metal complex in the heating vessel, the reaction vessel into which the metal complex is put and which has a periphery thereof coated with clay is placed in the heating vessel.
