Abstract:
     A process for preparing carbon nanotubes on the copmosite film of Au/Fe-series elements includes such steps as sputtering Fe or Co or Ni layer on the Si or SiO2 substrate, sputtering Au layer to obtain composite film catalyst, putting the substrate in resistance-wire CVD equipment, introducing hydrogen gas and methane, and growing high-purity multi-wall carbon nanotubes (20-200 nm) at 600-950 deg.C and 12-30 Tor for 10-120 min. Another approach is also disclosed. Its advantages are simple process, short period and low cost.
