| Abstract: | Carbon nanotube(CNTs)have been successfully grown by chemical vapor deposition with Fe/MgO as the catalyst.The CNTs grown under different conditions were characterized with scanning electron microscopy(SEM),high resolution transmission electron microscopy(HRTEM)and Raman spectroscopy.Influence of various factors,such as types of gaseous carbon sources,reacting temperrature and the concentration of Fe particles in MgO powder,on the CNT growth were tentatively studied. |
