Figure 4. Ni K-edge XAS analyses. (a) XANES spectra of Ni foil, Ni2O3, Ni(OH)2, FeNi(OH)2, and Pi−FeNi(OH)2. (b) Derived valence states of Ni. (c) k2-weighted Fourier-transformed EXAFS spectra. (d−f) Ni K-edge EXAFS fitting in R space for Ni(OH)2, FeNi(OH)2, and Pi−FeNi(OH)2 (dots: experimental data; lines: fitting; k2-weighted; without phase correction. (g−i) k2-weighted wavelet transform maps of Ni K-edge EXAFS signals for the samples.
