Cyclic voltammograms of Pb-Pt₃Au₁/MWCNTs/GCE (a), Pt₃Au₁/MWCNTs/GCE (b), and Pb-Pt/MWCNTs/GCE (c) in 1.0 M KOH aqueous solution (A) and 1.0 M CH₃OH + 1.0 M KOH aqueous solution (B,C), respectively. Currents in plans (A–C) are normalized to geometric area (A,B) and Pt active area (C), respectively. The inset in plan (A) is the CV of Pb-Au/MWCNTs/GCE in 1.0 M KOH aqueous solution. Scan rate: 50 mV s⁻¹.
