Abstract

Single‐walled carbon nanotubes (SWNTs) have been synthesized via a novel chemical vapor deposition (CVD) approach utilizing nanoporous, iron‐supported catalysts. Stable aqueous dispersions of the CVD‐grown nanotubes using an anionic surfactant were also obtained. The properties of the as‐produced SWNTs were characterized through atomic force microscopy and Raman spectroscopy and compared with purified SWNTs produced via the high‐pressure CO (HiPCO) method as a reference, and the nanotubes were observed with greater lengths than those of similarly processed HiPCO SWNTs.
