Evaluation of oxygen reduction activity of non-ideal Pt based catalyst thin films
Figure 1: SEM sequential images of a dealloying and degradation of PtCu3 electrocatalyst: a) as-synthesized, b) after 500 cycles between 0 and 1.2 V with 0.5 V/s, c) after 5k cycles between 0.6 and 1.2 V z 1 V/s in d) after 50k cycles between 0.6 and 1.2 V z 1 V/s in 0.1 M HClO4; (scale bar is 20 nm)
