Abstract Mixtures containing different weight ratios of single wall carbon nanotubes (SWCNT) and double wall carbon nanotubes (DWCNT) were prepared and studied by in situ Raman spectroelectrochemistry. Two components of the G′ mode in the Raman spectra, which can be resolved at high electrode potentials, were assigned to the signals from inner tubes of DWCNT and outer tubes of DWCNT together with SWCNT. The dependence of the ratios of these two components of the G′ mode on the nominal amount of… Expand

Selective and Scalable Chemical Removal of Thin Single-Walled Carbon Nanotubes from their Mixtures with Double-Walled Carbon Nanotubes.
It is shown that the amount of SWCNTs was reduced by about 35 % after lithium vapor treatment of the studied SWC NTs-DWCNTs mixture. Expand
Separation of double-wall carbon nanotubes by electronic type and diameter.
It is found that RZU processing followed by sequential bandgap and diameter sorting via ATPE provides samples of highest DWCNT enrichment, whereas single-step redox sorting of the same raw material through ATPE yields SWCNT/DWCNT mixtures of similar diameter and electronic character. Expand
Sorting of Double-Walled Carbon Nanotubes According to Their Outer Wall Electronic Type via a Gel Permeation Method.

In situ Raman spectroelectrochemistry as a tool for the differentiation of inner tubes of double-wall carbon nanotubes and thin single-wall carbon nanotubes.
The proposed spectroelectrochemical method based on the different change of the electronic structure of the inner tube in DWCNT and that of SWCNT during electrochemical charging, which is reflected in the Raman spectra, is a simple analytical tool for differentiation ofSWCNT and D WCNT in a mixture.

Electrochemical charging of individual single-walled carbon nanotubes.
