In Situ Dispersive EXAFS in Electrocatalysis: The Investigation of the Local Structure of IrO_x in Chronoamperometric Conditions as a Case Study

Figure 3

EXAFS (a) and FT (b) spectra of a sequence recorded within the first 40 seconds illustrated from the bottom to the top, separated by a time interval of ca. 6 seconds. The IrO₂ standard EXAFS and FT signals are represented as black lines. Measurements were carried out in basic medium for the potential step 0.2–0.9 V.
