Abstract
Single walled carbon nanotubes (SWNTs) have been successfully synthesized using a fluidized-bed method that involves fluidization of a catalyst/support at high temperatures by a hydrocarbon flow. When nickel-nitrate coated silica-gel particles and methane were used, SWNTs were found to grow densely on the entire surface of the support particles at 760°C, as revealed by Raman spectrometry and SEM analysis. This approach offers multiple advantages over the common fixed bed process, such as uniform gas-solid mixture and avoidance of catalyst particle sintering, and shows promise for the large-scale, potentially continuous, production of SWNTs, at high yield. © 2003 Elsevier B.V.
