Figures

Image of FIG. 1.
FIG. 1.

(a) Use of CNTs as the WE, with Pt as the counter electrode in a CV setup. A SCE was used as the reference. The inset illustrates a TEM image sample of the individual CNTs. (b) The correlation length of the CNTs decreases with increasing argon exposure. The inset depicts the Raman spectra for the as-prepared and argon irradiated (for times ) CNT electrodes.

FIG. 2.

(a) The deconvolution of observed CV spectrum, or argon exposed CNT electrodes, e.g., with a concentration of 6 mM and a (scan rate) of 20 mV/s, into the peak and double-layer currents, using a baseline current . (b) The variation of the total CNT capacitance with at various concentrations. (c) The variation of with concentration at various . (d) The correlates inversely to the (e.g., at a of 5 mV/s and 6 mM).
