Abstract: Provided is a method for highly efficiently producing highly pure single-walled carbon nanotubes. This method for producing carbon nanotubes by fluidized CVD includes: a step for heating a material (A) to 1200° C. or higher, in which the total mass of Al2O3 and SiO2 constitutes at least 90% of the total mass of the material (A) and the mass ratio of Al2O3/SiO2 is in the range of 1.0-2.3; and a step for bringing a gas, which is present in the environment in which the material (A) is being heated to 1200° C. or higher, into contact with a feed gas to generate carbon nanotubes.

Abstract: Provided is a nanosubstance-containing composition which exhibits excellent heat resistance in cases where a thermoplastic resin or a rubber is contained therein, while exhibiting high toughness in cases where a thermosetting resin is contained therein. A nanosubstance-containing composition according to the present invention contains (a) at least one component selected from the group consisting of thermoplastic resins, thermosetting resins and rubbers, (b) a compound having a reactive functional group and (c) a nanosubstance.
