a Ir L3-edge XANES spectra of IrO2(101) monolayer, Comm IrO2(Alfa Aesar) and Ir foil. b FT-EXAFS spectra of IrO2(101) monolayer, Comm IrO2(Alfa Aesar) and Ir foil at Ir L3-edge. Corresponding wavelet transforms for the k2-weighted Ir L3-edge EXAFS signals of c IrO2(101) monolayer, d Comm IrO2(Alfa Aesar), and e Ir foil. The color scale represents the wavelet transform signal intensity, with blue and black corresponding to high and low amplitudes, respectively. f The FT-EXAFS r space fitting curve of the crystal model in g. g Crystal structure of IrO2(101) monolayer. The refined structure model is simulated based on the XRD, FFT, and EXAFS analysis, Ir (yellow), O (red).
