Carbon nanotubes production by catalytic pyrolysis of benzene Original Research Article

Pyrolysis of benzene at ca 600–900 °C over Ni powder generated different types of carbon nanostructures possessing a wide range of morphologies. The effects of temperature and time on carbon nanotubes growth were evaluated. The deposited carbon yield was measured, and the quality of the nanotubes was analyzed by transmission electron microscopy (TEM).
