Selective growth of SWNTs on partially reduced monometallic cobalt catalyst

Chem Commun (Camb). 2011 Jan 28;47(4):1219-21. doi: 10.1039/c0cc02751k. Epub 2010 Nov 24.

Abstract

SiO(2) supported cobalt (Co) catalyst could be partially reduced and anchored by unreduced Co ions during a carbon monoxide (CO) chemical vapor deposition (CVD) process. This resulted in the formation of sub-nanometre metallic Co clusters catalyzing the growth of single-walled carbon nanotubes (SWNTs) with a narrow diameter distribution.
