Structure for holding catalyst particles for carbon nanotube production and method for producing same

Abstract

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