Abstract:
1. A process for producing single-walled carbon nanotubes, wherein a carbon source comprising an oxygen-containing organic compound or a mixture of a compound selected from the group consisting of water, NOX and SOX and a compound selected from the group consisting of hydrocarbons, pyridine and amine is brought into contact with a catalyst under a pressure or partial pressure of the carbon source comprising the oxygen-containing organic compound or the mixture of the compound selected from the group consisting of water, NOX and SOX and the compound selected from the group consisting of hydrocarbons, pyridine and amine of 0.1 to 200 Torr with heating at a temperature of from 500 to 900° C. in a reactor heated from the outside to yield carbon nanotubes consisting of 95% or more of single-walled carbon nanotubes, said catalyst being a powdered catalyst supported on a support material comprising zeolite or magnesia or a catalyst supported on a silicon substrate.
