Cyclic voltammograms of Pb-Pt₃Au_0.5/MWCNTs/GCE (a), Pb-Pt₃Au₁/MWCNTs/GCE (b), Pb-Pt₃Au₃/MWCNTs/GCE (c), Pb-Pt₃Au₅/MWCNTs/GCE (d), and Pb-Pt₃Au₇/MWCNTs/GCE (e) 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. Scan rate: 50 mV s⁻¹.
