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. 6. (a) Fe K-edge XANES spectra of FeN/SSiRC, FeN/PSiRC, FeN/SiRC and the reference samples. Inset is the enlarged view of the curves within the range of 7110–7125 eV; (b) FT-EXAFS spectra of FeN/SSiRC, FeN/PSiRC, FeN/SiRC and the reference samples; (c) FT-EXAFS fitting curves of FeN/SSiRC; (d) The wavlet transform of FeN/SSiRC, FeN/PSiRC, FeN/SiRC, and the reference samples.
