Methanol and ethanol tolerance tests. Cyclic voltammetry (CV) curves of the dendritic Pd59Cu30Co11 nanoalloys and the commercial Pt/C in N2-saturated 0.1 mol L−1 (M) potassium hydroxide (KOH) + 0.1 M methanol (CH3OH) (a) or ethanol (CH3CH2OH) (c) solution at 50 mV s−1. Oxygen reduction reaction (ORR) polarization curves of the dendritic Pd59Cu30Co11 nanoalloys and the commercial Pt/C in O2-saturated 0.1 M KOH + 0.1 M methanol (b) or ethanol (d) solution at 10 mV s−1 and rotation rate of 1600 rpm
