单壁碳纳米管（SWNTs）已经在气相催化过程中产生。用于单壁碳纳米管生长的催化剂通过五羰基铁在1-10大气压和800-1200摄氏度的压力下在加热的一氧化碳流中热分解而原位形成。单壁碳纳米管的产率和直径分布可以通过控制工艺参数来改变，并且已经产生了直径小至0.7 nm的单壁碳纳米管，与C-60分子的直径相同。这一过程显示了大量生产碳纳米管的巨大潜力。(C)1999 Elsevier Science B. V.保留所有权利。
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.
