(A) CVs recorded at room temperature in 0.1 M HClO4 solution at a sweep rate of 50 mV/s. (B) ORR polarization curves recorded at room temperature in an O2-saturated 0.1 M HClO4 aqueous solution at a sweep rate of 10 mV/s and a rotation rate of 1600 rpm. (C) ECSAs, (D) mass activities, and (E) specific activities of PtNiCo NWs/C, PtNi NWs/C, Pt NWs (1 nm)/C, Pt NWs (4.5 nm)/C, and commercial Pt/C.
