Abstract EN
Multiwalled carbon nanotubes (MWCNTs) were synthesized by CVD on industrially manufactured highly crystalline vapor-grown carbon fibers (VGCFs).
Two catalyst metals (Ni and Fe) and carbon precursor gases (C2H2 and CO) were studied.
The catalysts were deposited on the fibers by sputtering and experiments carried out in two different reactors.
Samples were characterized by electron microscopy (SEM and TEM).
Iron was completely inactive as catalyst with both C2H2 and CO for reasons discussed in the paper.
The combination of Ni and C2H2 was very active for secondary CNT synthesis, without any pretreatment of the fibers.
The optimal temperature for CNT synthesis was 750∘C, with total gas flow of 650 cm3min−1 of C2H2, H2, and Ar in 1.0:6.7:30 ratio.
