    摘要: [Problems to be Solved]There is provided a method for production of a carbon nanotube, which allows for production of the carbon nanotube in a large scale and at a low cost.[Solution]The temperature of a catalyst loaded on a support is raised by heating the support and a raw material gas containing a carbon source is supplied on the catalyst to synthesize the carbon nanotube. The synthesized carbon nanotube is recovered, and after the recovery, the catalyst is subjected to a regeneration treatment to repeatedly utilize the support. Since the catalyst deteriorates, the catalyst is regenerated periodically or nonperiodically during the production. The regeneration treatment of the catalyst involves an oxidation treatment of the catalyst. Further, after the oxidation treatment, a reducing gas is fed to and brought into contact with the catalyst surface to reduce the catalyst. As the support, a honeycomb is used.

    摘要: The present disclosure is related to a method for forming a catalyst nanoparticle on a metal surface, the nanoparticle being suitable for growing a single nanostructure, in particular a carbon nanotube, the method comprising at least the steps of: providing a substrate, having a metal layer on at least a portion of the substrate surface, depositing a sacrificial layer at least on the metal layer, producing a small hole in the sacrificial layer, thereby exposing the metal layer, providing a single catalyst nanoparticle into the hole, removing the sacrificial layer. The disclosure is further related to growing a carbon nanotube from the catalyst nanoparticle.
