Title:

CATALYST FOR PRODUCING CARBON NANOTUBE

Document Type and Number:

WIPO Patent Application WO/2024/080789

Kind Code:

A1

Abstract:

The present invention relates to: a catalyst for manufacturing a carbon nanotube comprising a support, a first active layer formed on the surface of the support, and a second active layer formed on the surface of the first active layer, wherein the first active layer comprises cobalt oxide and the second active layer comprises aluminum oxide; and a method for producing a carbon nanotube using the catalyst. The catalyst of the present invention can synthesize low-diameter carbon nanotubes more uniformly and efficiently.
