Abstract
A method for manufacturing carbon nanotubes of the present invention includes 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. As the metal complex used in a method for manufacturing carbon nanotubes of the present invention, nickel stearate or nickel benzoate can be named, for example. According to the method for manufacturing carbon nanotubes of the present invention, it is possible to manufacture carbon nanotubes using an inexpensive heating device within a short time.
