CNTsSWCNTs MWCNTsProduction Methods method Vaporization method Vapor Deposition (CVD)PreparationCVD methods have been successfully applied in making carbon nanotubes. The growth process with this method involves heating a catalyst material to high temperatures in a tube furnace and flowing a hydrocarbon gas through the tube reactor for a period of time. Materials grown over the catalyst are collected upon cooling the system to room
