Figure 4. X-ray absorption spectra for as-prepared, Cl2-treated and H2-treated catalysts.

Figure 4

XANES (a), EXAFS (b) and Fourier transforms (FTs) of EXAFS (c). Dashed lines show spectra for reference materials: Fe foil (bcc structure) and hydrated Fe (III) chloride (FeCl3·xH2O). Structures of reference materials are shown in the insets of a.
