Fig. 9. The XANES spectra of DMC–pure and DMC–PAM1 catalysts (A) Co K-edge (B) Zn K-edge, the EXAFS spectra (k2-weighted and the Fourier transformed over a k-range of 3.0–11.4 Å−1) of DMC–pure and DMC–PAM1 catalysts (C) Co K-edge (D) Zn K-edge, and the model fits the EXAFS data (the Fourier filtered over a k-range of 3.7–11.1 Å−1) of the local atomic structure around Zn atoms (E) DMC–pure (F) DMC–PAM1.
