  • Catalyst for synthesizing carbon nanotube and method of synthesizing carbon nanotube
    Patent number: 11117120
    Abstract: A catalyst for synthesizing a carbon nanotube includes a support containing a metal, and an active metal impregnated on the support. The active metal includes cobalt and manganese. A surface molar ratio of the active metal relative to the metal of the support is 40% or less of a bulk molar ratio of the active metal relative to the metal of the support. A carbon nanotube having high purity and low resistance is obtained from the catalyst.
    Type: Grant
    Filed: October 30, 2018
    Date of Patent: September 14, 2021
    Assignees: SK Innovation Co., Ltd., SK Global Chemical Co., Ltd.
