Abstract:
1. A method of synthesizing multi-walled carbon nanotubes, comprising: driving a reaction in a Chemical Vapor Deposition (CVD) furnace; generating at least one multi-walled carbon nanotube through the reaction in the CVD furnace; depositing a catalyst on the CVD furnace, wherein the iron catalyst source is a cyclopentadienyliron dicarbonyl dimer [CpFe(CO) driving a carbon source with a carrier gas to the CVD furnace; and decomposing the carbon source in the presence of the catalyst, under a sufficient gas pressure for a sufficient time, to grow the multiwalled carbon nanotube at a target temperature, wherein the carbon source is at least one of a carbon-source gas and an auxiliary carbon source.
