Figure 4
FTIR spectra of the commercial IrO2 catalysts during the OER. To clearly present the change of FTIR spectra, a constant y-axis offset method is employed to separate plots along the y-axis, where the y-axis offset values for the plots under OCV, 1.40 V, 1.55 V and 1.60 V are 0, 0.1, 0.2 and 0.3, respectively.
