The deposition rate of carbon nanotubes in a tube flow CVD reactor was studied over different temperatures and inlet gas concentrations with a focus on particle size and the number nanotube walls per particle. It was found that larger particles and higher numbers of walls increased the use of carbon and required a higher concentration of the carbon feedstock gas, methane. These results show that optimizing reactor conditions will require tailoring the feedstock gas concentrations according to the particle size and expected number of walls per nanotube in order to ensure that there is enough carbon to facilitate nanotube forming reactions.
