More Information
Summary:The present invention relates to a catalyst for producing carbon nanotubes, a method for preparing the catalyst, and a method for producing carbon nanotubes using the catalyst which includes a support, and an active layer formed on a surface of the support, wherein the active layer contains CoO and Co3O4, and has, through XRD pattern measurement, one peak at 2θ=35° to 38°, and one peak at 2θ=41° to 44°, and a proportion of CoO among the CoO and Co3O4 is 55 at % or more. The catalyst according to the present invention can efficiently synthesize low-diameter carbon nanotubes.
