| Abstract: | Carbon nanotube ropes had been synthesized with the presence of catalyst Fe(NO3)3 by using acetylene as the carbon source at 750 ℃.The as-received rope-type carbon nanotubes were characterized by scanning electron microscopy.The diameters of the as-produced carbon nanotubes range from 100 nm to 200 nm,and the lengths range from 10 μm to 20 μm.The tentative growth mechanism for rope-type carbon nanotubes had been suggested and discussed. |
