Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 4. In situ spectral characterization (40 mL·min−1, 5% NH3/Ar). a) XANES spectra of the Fe K-edge on Fe/MgO and Fe foil. b) EXAFS spectra of the Fe K-edge on Fe/MgO and Fe foil. c) XANES spectra of the Fe K-edge on Fe1Cu0.5/MgO and Fe foil. d) EXAFS spectra of the Fe K-edge on Fe1Cu0.5/MgO and Fe foil. e) Wavelet transformed k3-weighted EXAFS spectra of Fe1Cu0.5/MgO and Fe foil.
