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. Structural characterization of as-prepared catalysts. (a) XRD patterns, (b) XRD Rietveld refinement spectra of Co/Co3O4-NCF, and (c) Co 2p high-resolution XPS spectra of Co-NCF, Co/Co3O4-NCF and Co3O4-NCF. (d) The Co k edge XANES spectra, (e) FT-EXAFS spectra, (f) k edge EXAFS oscillation functions curves, and (g) WT-EXAFS spectra for Co/Co3O4-NCF and its reference samples (Co foil, Co3O4, CoO).
