Chalcogen-grafted carbon material as well as their functionalized forms are described along with processes for their preparation. More specifically, the chalcogen is covalently linked to the carbon scaffold of a polyaromatic carbon via C═X and/or C—X—C bonds. Processes for their preparation include a single thermal treatment without the use of strong acids or anhydrous solvents.

Chalcogen-grafted carbon materials and processes for their preparation

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 P/Pis about 5&#xd7;10or less, wherein Pis the partial pressure oxidizing species in the atmosphere and Pis 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.
