摘要
Methods and systems of preparing a catalyst to be used in the synthesis of carbon nanotubes through Chemical Vapor Depositions are disclosed. The method may include a mixture comprising at least one of an iron catalyst source and a catalyst support. In another aspect, a method of synthesizing multi-walled carbon nanotubes using the catalyst is disclosed. The method may include driving a reaction in a CVD furnace and generating at least one multi-walled carbon nanotube through the reaction. The method also includes depositing the catalyst on the CVD furnace and driving a carbon source with a carrier gas to the CVD furnace. The method further includes decomposing the carbon source in the presence of the catalyst under a sufficient gas pressure for a sufficient time to grow at least one multi-walled carbon nanotube.
