Chemical Vapor Deposition Synthesis of Carbon Nanotubes Using Iron Catalysts

Single-walled carbon nanotubes (SWNTs) were synthesized via a novel chemical vapor deposition (CVD) technique incorporating iron catalysts. Stable aqueous solutions of the nanotubes using the anionic surfactant sodium dodecylbenzene sulfonate were also obtained, and the properties of as-produced SWNTs were documented through atomic force microscopy and Raman spectroscopy and compared with purified HiPCO SWNTs as a reference.
