Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 2. Electronic state and atomic structure characterization of the prepared sample. (a) C K-edge soft XANES spectra of Fe-O-CN. (b) O K-edge soft XANES spectra of Fe-O-CN. (c) XANES spectra of the normalized Fe K-edge of Fe foil, FeO, Fe3O4, Fe2O3, Fe-CN and Fe-O-CN. (d) The corresponding Fourier transform EXAFS spectra. (e) EXAFS fitting curves of Fe-CN and Fe-O-CN in the R space. (f) EXAFS fitting curves of the Fe-O-CN. (g) Wavelet transform (WT) plots of Fe foil, FeO, Fe3O4, Fe-CN and Fe-O-CN.
