EFC-ICP-MS comparison of metal dissolution from Pt-M/C FCS electrocatalysts in the as-purchased state and after PCA

Close-ups of a single cycle from 0.05 to 1.4 V_RHE for all Pt-M/C electrocatalysts in the (A–D) as-purchased state and (E–H) after PCA (200 cycles in 0.1 M HClO₄, 0.05–1.2 V_RHE, 300 mV s⁻¹). See also Supplemental informationFigures S21–S24 for further comparisons of EFC-ICP-MS experiments. The colors (Pt-Cu = blue, Pt-Fe = orange, Pt-Ni = red and Pt-Co = magenta) correspond to the ones used for the graphs and borders in all of the figures.
