The amperometric response of Au-Ag/MWNT working electrode. (A) Curves of CV were obtained with different working electrodes (MWNTs/GCE, Au-Ag/GCE, and Au-Ag/MWNTs/GCE); (B) the amperometric response of Au-Ag/MWNT working electrode with different molar ratios between Au-Ag and MWNTs (3:1, 2:1, 1:1, 1:2, and 1:3, respectively).
