title = "Single-walled carbon nanotube growth from composite catalysts in diffusion flames",
abstract = "Silicon is investigated as catalyst particle additive for synthesis of single-walled carbon nanotubes in inverse diffusion flames. Silicon is often used as a substrate in supported-catalyst processes to promote nanotube growth but this study demonstrates that it can also be beneficial for gas-phase nanotube synthesis in diffusion flames. An oxy-fuel inverse diffusion flame is employed to provide a soot-free, carbon-rich environment for nanotube growth. Iron and silicon precursors are added to the fuel stream for nucleation of iron/silicon composite catalyst particles. By adjusting the temperature and species concentration gradients, a desirable level of oxidation of the particles can be achieved in a small region of the flame. In this region, over 90\% of catalyst particles produce a single-walled carbon nanotube while less than 10\% of particles produce a nanotube if the catalyst consists of only iron and oxygen.",
