Hj. Huang et al., Large-scale rooted growth of aligned super bundles of single-walled carbonnanotubes using a directed arc plasma method, CHEM P LETT, 343(1-2), 2001, pp. 7-14
We have modified the conventional arc-discharge method for the production o
f single-walled carbon nanotubes (SWNTs) by using a bowl-shaped cathode tha
t can direct the are plasma in a specified direction and using a combinatio
n of cobalt, nickel, iron and cerium as an efficient catalyst, with sulfur
as a promoter and tin as a nanowelding element. Under optimized conditions,
SWNT super bundles can be efficiently produced with carbon-to-tube yields
of over 70%. (C) 2001 Elsevier Science BN. All rights reserved.
