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. 3. (a and b) Normalized XANES spectra and (c and d) Fourier transforms of EXAFS spectra at the Co K-edge and Fe K-edge of Co3S4/FeS@CoFe/NC catalyst and the reference materials at R space. Wavelet transform (WT) of (e) Co K-edge and (f) Fe K-edge EXAFS spectra for Co foil, Fe foil, CoPc, FePc, and Co3S4/FeS@CoFe/NC, respectively. EXAFS curves represent fitted data based on (g) Co K-edge and (h) Fe K-edge and experimental data, with the fitted structure of Co3S4/FeS@CoFe/NC catalyst at the insets.
