A Fe2O3/Al2O3 binary aerogel was used as a catalyst for the synthesis of singlewalled carbon nanotubes (SWCNTs) by the catalytic decomposition of CH4H2 and a CH4H2water mixture at 900℃ for 3min. The influence of water vapor on the growth of SWCNTs was investigated by characterizing the morphology and structure of the carbon products using scanning electron microscopy, Xray diffraction, transmission electron microscopy, and Raman spectroscopy. Results show that SWCNTs with a high purity were synthesized under the mixed atmosphere of CH4H2water when the amount of water vapor present was controlled by bubbling H2 through water. The yield and microstructure of the asformed carbon products can be correlated with the composition of the reaction mixture.
