Abstract

Gas-phase pyrolysis of acetylene along with a metallocene or with a binary mixture of metallocenes in flowing Ar or Ar + HImage at 1100Image C yields single-walled carbon nanotubes. Pyrolysis of Fe(CO)Image -acetylene mixtures in Ar at 1100Image C also gives single-walled nanotubes. The diameter of the nanotubes is generally around 1 nm, showing thereby that on pyrolysis under the dilute conditions employed, the organometallic precursors give rise to very fine metal particles essential for the formation of such nanotubes.
