STUDY ON SEMI-CONTINUOUS PREPARATION OF CARBON NANOTUBE BY FLOATING CATALYST METHOD

Semi continuous preparation of carbon nanotubes by floating catalyst method (FCM) was studied. All samples were analyzed by transmission electron microscopy (TEM). According to the grow mechanism of carbon nanotubes, a systemic discussion about the effect of three technical parameters on forms, yield and distribution of external diameter of products was carried out. At last, the optimal technical parameters were obtained under the condition of the carbon source C 6H 14 . Carbon nanotubes with diameter of 30 nm～60 nm can be obtained by using FCM.
