Figure 2
Operando PDF data collected during stepped chronoamperometry at increasingly high absolute values of the applied electrical potential (a)–(b) during the eCO2RR in a CO2-saturated aqueous 0.1 M KHCO3/K2CO3 electrolyte and (c)–(d) under oxidative potentials in an OER experiment in Ar-saturated electrolyte. (a) and (c) show the longer-range correlations while (b) and (d) are magnifications of the local regions. Gray lines in (d) highlight regions of structural changes. The PDF data are the last 180 s of each potential step summed (see the supporting information for details of the time voltage evolution). |
