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) H-D exchange spectra; (b) Co K-edge XANES spectra with Co foil as reference. (c, d) k3-weighted FT-EXAFS spectra of Co9S8-5FeOx/C-1 and Co9S8/C-1 at the Co K-edge. (e) Wavelet transforms (WTs) for k3-weighted Co K-edge EXAFS of Co9S8-5FeOx/C-1 and Co9S8/C-1.
