The performance of cyclic voltammograms. (A) Cyclic voltammograms of the Au-Ag/MWNT working electrode at various scan rates from 20 to 200 mV/s in 0.1-mol/L KCl solution. All potentials are given versus SCE; (B) displays the dependence of the redox peak currents (Ip) on the scan rates (v). The inset shows redox peak currents plot with scan rate at a range of 20 to approximately 200 mV/s. (C) Cyclic voltammograms of Au-Ag/MWNTs/GCE were exposed to various concentrations of 2-butanone at ranges of 0% to approximately 20% (v/v) in 0.1-M KCl solution; (D) the linear calibration plot of the peak current against butanone. The inset shows the curve of the peak current corresponding to different concentrations of 2-butanone.
