“…The radial modes present near 180 cm -1 can be correlated with SWNT diameters. [24][25][26][27][28] The peaks present for the annealed sample suggest that the nanotube diameter in the sample range from 1.13 to 1.53 nm, with an average size of 1.33 nm. This is calculated with d ) 234/ν, 29 where d is the tube diameter in nanometers and ν is in wavenumbers.…”

A purification method has been developed that provides for the removal of metal catalysts and impurity carbon from laser-oven-grown single-wall carbon nanotube (SWNT) material. The oxidation rate of SWNTs in air at elevated temperatures is correlated to the metal content of the sample. Sample purity is documented with SEM, TEM, electron microprobe analysis, Raman, and UV-vis-near-IR. We also note that the relative intensity of the electronic transitions in the near-infrared to the continuum absorption at 400 nm in the UV serves as a useful monitor of the perturbation of the sidewall π-electron density of SWNTs due to sidewall substitution and/or oxidation.

“…The removal of impurities by electrophoretic or chromatographic methods can be quite challenging. 50,51 The density-gradient ultra-centrifugation technique is proving to be a scalable process to separate carbon nanotubes based on their electronic structure.…”

In its conducting form, carbon has proven to be a versatile, robust and high performing electrode material in areas such as energy conversion, energy storage and even medical bionics. In our laboratories we have been interested in the fabrication and utilization of nanostructured electrodes based on more recently discovered forms of carbon. These include carbon nanotubes and graphene.
