Figure 2.

Surface stress response (Δf) of a (111)-textured Pt cantilever electrode to potentiostatic cathodic pulses from a starting potential of −0.20 V vs SSE in 0.1 mol/L KHCO3 saturated with (a) Ar (CO-free) or (b) CO. The pulse duration was 100 s, followed by a return pulse to −0.20 V for 75 s. (c) The average net stress change for both cathodic and return pulses shown in panels (a) and (b).
