evaluation of catalyst ball-milling process on growth and diameter of carbon nanotubes on iron nanoparticles
نویسندگان
چکیده
in this study, we describe the growth of carbon nanotubes on commercial iron nanoparticles without carbon shell (fe (nm), size 2o3 and fe* (nm)/mgo) was carried out by mixing commercial fe* nanoparticles (as catalyst) with al2o3 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 925 ˚c, but it could increase the range of growth temperature from 865 ˚c to 975 ˚c.
