Abstract
Singlewalled carbon nanotubes are largely synthesized on Fe-Mo/MgO catalysts by catalytic decomposition of CH4 in H2. Raman data revel that the as-prepared SWNTs have a diameter of about 0.7-1.2nm. It is found that the diameter of the as-prepared SWNTs can be controlled mainly by adjusting the molar ratio of Fe-MO versus the MgO support. The experimental results was documented with scanning electron microscopy(SEM), X-ray Diffractometer(XRD) and Raman spectroscopy.
