The ORR performance of Ru@Pt/C (8.798 wt% Pt), PtRu/C-D (25.34 wt% Pt), Pt/C-P (1.01 wt% Pt) and JM-Pt/C (20 wt% Pt).
(a) The original oxygen reduction linear sweep voltammetry was recorded in O2-saturated 0.1 M HClO4 at room temperature, at a rotation speed of 1600 rpm and a scanning rate of 10 mV s−1. (b) The mass activity and turnover frequency values for Ru@Pt/C, PtRu/C-D, Pt/C-P and JM-Pt/C towards the reduction of oxygen, calculated from the current density at 0.9 V (vs. RHE).
