We have in-situ observed infrared absorption spectra for cobalt catalyst surface during growing carbon nanotubes by the thermal chemical vapor deposition method to elucidate the growth mechanism of CNT on cobalt catalysts. CH_3OH and CH_4 gases were used as a source. CNT grew when CH_3OH gas was used while it did not grow when CH_4 gas was used. We observed two peaks due to oxygen adsorbed on cobalt surface and CoOCH_3 species when CNT was grown. The infrared absorption spectral changes indicate that the CoO-C bond plays an important role in the CNT growth mechanism on cobalt catalysts and infrared absorption spectroscopy is capable of sensitive analysis of the chemical reaction on cobalt catalysts.
