Fig. 2. — Structural analyses. (A) XANES of Ir L₃-edge spectra; the inset is used to confirm the Ir valence by L₃-edge area integration. (B) Fourier transform of k²-weighted Ir L₃-edge EXAFS data. (C) Experimental and best-fitting IrRu-N-C and Ir-N-C results of the Ir L₃-edge EXAFS. (D) XANES of Ru K-edge spectra; the inset is used to evaluate the Ru valence. (E) Fourier transform of k²-weighted Ru K-edge EXAFS data. (F) Experimental and best-fitting IrRu-N-C and Ir-N-C of the Ru K-edge EXAFS results.
