Synthesis of Carbon Nanotubes by Chemical Vapor Deposition (CVD).

Nanotubes form in the arc and collect on the anode, along with a host of other carbon byproducts. The nanotubes that are synthesized by this means are typically very ropy and multi-walled. Chemical vapor deposition (CVD) is the means of synthesis that is of interest for this study. CVD synthesis is achieved by taking a carbon species in the gas phase and

Catalytic Chemical Vapor Deposition of Single-Wall Carbon

May 02, 2006 · We report surface-bound growth of single-wall carbon nanotubes (SWNTs) at temperatures as low as 350 °C by catalytic chemical vapor deposition from undiluted C 2 H 2. NH 3 or H 2 exposure critically facilitates the nanostructuring and activation of sub-nanometer Fe and Al/Fe/Al multilayer catalyst films prior to growth, enabling the SWNT nucleation at lower temperatures.
