Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 4. (a) Normalized Ni K-edge XANES spectra of p-β-NiMoO4-A, p-β-NiMoO4, α-NiMoO4, p-α-NiMoO4, NiO, and Ni foil. (b) The corresponding FT-EXAFS spectra. (c,d) The fitting curves of p-β-NiMoO4-A and p-β-NiMoO4. (e,f) Wavelet transform (WT)-EXAFS plots of p-β- NiMoO4-A and p-β-NiMoO4. (g) Schematic diagram of electronic coupling for Ni−O−Mo in p-β-NiMoO4-A and p-β-NiMoO4.
