摘要：
Single-walled carbon nanotubes (SWNTs) have been produced in a gas-phase catalytic process. Catalysts for SWNT growth form in situ by thermal decomposition of iron pentacarbonyl in a heated flow of carbon monoxide at pressures of 1-10 atm and temperatures of 800-1200 degrees C. The SWNT yield and diameter distribution can be varied by controlling the process parameters, and SWNTs as small as 0.7 nm in diameter, the same as that of a C-60 molecule, have been generated. This process shows great promise for bulk production of carbon nanotubes. (C) 1999 Elsevier Science B.V. All rights reserved.
