In situ TPO/Raman to characterize single-walled carbon nanotubes
نویسندگان
چکیده
Temperature programmed oxidation (TPO) coupled with in situ Raman spectroscopy has been used as an effective qualitative and quantitative analysis of raw and purified single-walled carbon nanotubes (SWNT) samples. The incorporation of Raman facilitates the identification of the nature of the oxidation peaks present in a TPO profile. Using different samples it was possible to evaluate the potential of the technique for quantifying different impurities in the SWNT samples as well as in SWNT-polymer composites. 2003 Elsevier B.V.

Catalytic CVD generation of high-purity single-walled carbon nanotubes (SWNTs) without use of an electric furnace or a hot-filament is demonstrated. High-purity SWNTs were generated from alcohol used as a carbon source with Fe/Co particles supported on zeolite by Jouleheating of a silicon base plate. This technique was applied for an in situ measurement of Raman scattering during the growth sta...
