  • Method of manufacturing carbon nanotubes using electric arc discharge
    Patent number: 10822236
    Abstract: Disclosed is a method for producing CNTs by an electric arc discharge method. The synthesis gas for the arc discharge includes nitrogen and oxygen gases. The oxygen gas in the synthesis gas is converted to reactive oxygen species by the arc discharge and chemically reacts with amorphous carbon. Accordingly, the formation of amorphous carbon is suppressed when CNTs are formed on the cathode, and thus, high crystallinity of CNTs can be secured.
    Type: Grant
