Abstract:

In this study, we describe the growth of carbon nanotubes on commercial iron nanoparticles without carbon shell (Fe (nm), size ۲O۳ and Fe* (nm)/MgO) was carried out by mixing commercial Fe* nanoparticles (as catalyst) with Al۲O۳ and MgO powders (as supports)by using ball-milling method. The results show in spite of the fact that ball-milling process can have negative effects on diameter and morphology of synthesized CNTs at ۹۲۵ ˚C, but it could increase the range of growth temperature from ۸۶۵ ˚C to ۹۷۵ ˚C.
