Growth of high quality CNTs using pure propane is demonstrated over a range of growth temperatures (600–1100 °C). SWCNT and MWCNT volumes in the grown material can by tuned using the growth temperature. The SEM image shows CNTs grown at 900 °C with both SWCNTs and MWCNTs visible. Increasing temperature yields higher depositions of disordered carbon material besides NTs.
