The methanol oxidation performance of Ru@Pt/C (8.798 wt% Pt), PtRu/C-D (25.34 wt% Pt), Pt/C-P (1.01 wt% Pt) and commercial JM-Pt/C (20 wt% Pt).
(a) The original cyclic voltammograms in a solution of 0.1 M HClO4 and 1 M CH3OH, at room temperature and a scanning rate of 50 mV s−1. (b) The mass activity of Ru@Pt/C, PtRu/C-D, Pt/C-P and JM-Pt/C towards the anodic oxidation of methanol; the shaded bars were calculated based on the forward peak current density and the unshaded bars were based on the backward peak current density.
