Electrochemical results of Pt-decorated Co-Pd nanocatalyst. a Initial and final oxygen reduction reaction (ORR) polarization curves of commercial Pt/C and Pt-decorated Co-Pd (Co@Pd-Pt/carbon nanotube (CNT)) catalysts. b ORR polarization curves of Co@Pd-Pt/CNT at selected accelerated degradation test (ADT) cycles. c Changes of onset potential and half-wave potential of Co@Pd-Pt/CNT at selective ADT cycles. d Changes of kinetic current density of Co@Pd-Pt/CNT at selective ADT cycles. e Comparison of ORR mass activity of commercial Pt/C and Co@Pd-Pt/CNT at selected ADT cycles. f Cyclic voltammetry (CV) curves of Co@Pd-Pt/CNT at selected ADT cycles
