MOR studied at NPG obtained from Ag₇₇Au_23–xPt_x (x = {1, 2, 3}) at 298 K with and without surface segregation of Pt during treatment at 425 °C for 2 h. (A) Variation of ligament size and surface Pt content. (B) Comparison of peak current densities before and after Pt surface segregation. Peak current densities are calculated with respect to the true surface area. v = 10 mV s¹, 1 mol L¹ MeOH + 5 mol L¹ KOH, quiescent solution. Reproduced in part with permission from ref (525).
