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 5×10−26 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.
