Figure 19: Voltammetry curves for PtMLPd/C (blue), PtMLPdIr/C (red), and Pt/C (black) in deaerated 0.1 M HClO4 solution. Scan rate, 20 mVs−1. (b) Polarization curves for the ORR on PtMLIrPd/C (green), PtMLPd/C (blue), PtMLPdIr/C (red), and Pt/C (black) at 1,600 rpm in oxygen-saturated 0.1 M HClO4 solution. Scan rate, 10 mVs−1 [58].
