  • Publication number: 20110038785
    Abstract: To efficiently and easily manufacture carbon nanotubes oriented in one direction. A method for manufacturing carbon nanotubes is characterized by including the steps of: bringing crystalline metal oxide particles into contact with a solution containing metal ions serving as a catalyst for forming carbon nanotubes, thereby attaching the catalyst to the surfaces of the metal oxide particles; subjecting the surfaces of the metal oxide particles to which the catalyst is attached to a CVD method or a combustion method, thereby forming carbon nanotubes on the surface of each of the metal oxide particles and resulting in producing metal oxide particles each supporting carbon nanotubes grown substantially perpendicularly to the surface of the metal oxide particle and in parallel with each other; and removing metal oxide particles from the metal oxide particles supporting carbon nanotubes.

  • Publication number: 20090022651
    Abstract: Carbon nanotubes are more efficiently produced with a simpler apparatus. The process, which is for producing carbon nanotubes by the combustion method, is characterized by comprising: a step in which a catalyst-supporting powder comprising a base powder and a catalyst supported on the surface thereof is prepared; a step in which the catalyst-supporting powder is deposited on a porous support (2) having through-holes through which a flame passes, so that the powder particles are held in the through-holes without tenaciously adhering to one another; a step in which the porous support (2) having the catalyst-supporting powder held thereon is disposed in a combustion oven (1) in which one end (1b) is open; and a step in which a carbon-containing flame is generated in a burner part (3) disposed at the other end (1a) of the combustion oven (1) and the flame is fed to the through-holes of the porous support (2) to produce carbon nanotubes on the surface of the catalyst-supporting powder present in the through-holes.
