Abstract:
There are provided an easily producible structure holding catalyst particles used for production of carbon nanotubes, and a method for producing the same. The method for producing the structure (11) holding catalyst particles of the present invention used for production of carbon nanotubes includes a step of forming a catalyst particle forming layer (3) containing Si, Al, and Fe, and a step of performing a heat treatment on the catalyst particle forming layer (3) in an atmosphere containing oxygen, to form catalyst particles (2) containing Fe. The catalyst particles are held by the catalyst particle forming layer so that the catalyst particles are partially embedded in the catalyst particle forming layer (3). The size and the number of the catalyst particles (2) containing Fe are controlled by adjusting the amount of oxygen contained in the atmosphere for the heat treatment. Thus, the structure (11) holding catalyst particles is formed easily.
