摘要: There is provided a high-purity carbon nanotube, which can be produced with simple purification by causing graphite to be hardly contained in crude soot obtained immediately after being synthesized by arc-discharge, and a method for producing the same. Soot containing carbon nanotubes produced by arc-discharge using an anode which contains amorphous carbon as a main component is heated at a temperature of not lower than 350° C. to be burned and oxidized, immersed in an acid, heated at a temperature, which is not lower than the heating temperature in the previous burning and oxidation and which is not lower than 500° C., to be burned and oxidized, and immersed in an acid again.
