Title: Utilization of iron oxide film obtained by CVD process as catalyst to carbon nanotubes growth

Thin films of Fe{sub 2}O{sub 3} were obtained on silica glass substrates through the thermal decomposition of ferrocene in air. These films were characterized by Raman spectroscopy and X-ray diffractometry (XRD), and subsequently used as catalyst on the growth of carbon nanotubes, using benzene or a benzene solution of [Fe{sub 3}(CO){sub 12}] as precursor. A great amount of a black powder was obtained as product, identified as multi-walled carbon nanotubes by XRD, Raman spectroscopy and transmission electron microscopy. The carbon nanotubes formed through the pyrolysis of the [Fe{sub 3}(CO){sub 12}] solution were identified as structurally better than the one obtained by the pyrolysis of pristine benzene. - Graphical abstract: Thin films of Fe{sub 2}O{sub 3} were obtained on silica glass substrates through the thermal decomposition of ferrocene in air, and subsequently used as catalyst on the growth of carbon nanotubes.
