A possible route to large-scale production of SWNTs through a combination of the substrate and floating catalyst methods

J Nanosci Nanotechnol. 2004 Jan-Feb;4(1-2):132-5. doi: 10.1166/jnn.2004.019.

Abstract

We describe a possible route for large-scale synthesis of single wall carbon nanotubes (SWNTs) by a combination of the substrate and floating methods. The template prohibits metal particle aggregation, resulting in high-purity SWNT growth, and the three-dimensional floating seeded state of the template induces improved yields of SWNTs in a semi-continuous system. The SWNTs obtained by this method exhibit large variations of texture (isolated tubes and bundles) and a wide range of diameters (0.4-4 nm).
