  • METHOD OF GROWING A GRAPHENE COATING OR CARBON NANOTUBES ON A CATALYTIC SUBSTRATE
    Publication number: 20160376156
    Abstract: A method of growing a graphene coating or carbon nanotubes on a catalytic substrate by chemical vapor deposition is provided. In the method, the chemical vapor deposition is carried out in an atmosphere in which a ratio Pox/Pred is about 5×10?6 or less, wherein Pox is the partial pressure oxidizing species in the atmosphere and Pred is the partial pressure of reducing species in the atmosphere. A catalytic substrate coated with a graphene coating grown according to this method is also provided.
