Fig. 9. Comparison between experimental and best-fit curves for Cu-CHA 0.2_15 after exposure to the NO/O2 mixture at 200 °C from LCF analysis of (a) the normalized XANES and (b) the k2χ(k) EXAFS spectra. The LCF residuals and the scaled components corresponding to the Z[CuIINO3] and Z2CuII species are reported in both working spaces.
