“…The interfacial capacitance from the voltammetric responses is 0.64 mF ¥ cm À2 for the MWNTs electrode, which is much higher than that of the glassy carbon electrode or the bare Ta substrate electrode. This result implies that carbon nanotubes exhibit a very high specific capacitance [39] and can be used as electrochemical devices.…”

The voltammetric behaviors of uric acid (UA) and l-ascorbic acid (l-AA) were studied at well-aligned carbon nanotube electrode. Compared to glassy carbon, carbon nanotube electrode catalyzes oxidation of UA and l-AA, reducing the overpotentials by about 0.028 V and 0.416 V, respectively. Based on its differential catalytic function toward the oxidation of UA and l-AA, the carbon nanotube electrode resolved the overlapping voltammetric response of UA and l-AA into two well-defined voltammetric peaks in applying both cyclic voltammetry (CV) and differential pulse voltammetry (DPV), which can be used for a selective determination of UA in the presence of l-AA. The peak current obtained from DPV was linearly dependent on the UA concentration in the range of 0.2 mM to 80 mM with a correlation coefficient of 0.997. The detection limit (3d) for UA was found to be 0.1 mM. Finally, the carbon nanotube electrode was successfully demonstrated as a electrochemical sensor to the determination of UA in human urine samples by simple dilution without further pretreatment.

“…It is of interest to explore the properties of carbon nanocomposite electrodes to see if they might exhibit new properties, due to the high edge/surface area ratio of such materials. Marken et al, 2001 have evaluated CNFs (obtained by ambient pressure CVD method) as novel electrode materials for electrochemical applications (porous, pressed onto a glassycarbon substrate and non-porous, embedded in a solid paraffin matrix). They exhibit low BET surface areas and high electrochemical capacitances due to the fact that the spaces between the fibers allow the penetration of electrolyte solution.…”
