Figure 3. (a) Normalized XANES spectra at the Ni K-edge for Ni−N2, Ni−N3, and Ni−N4. (b) Fourier transform EXAFS spectra for Ni-N2, Ni- N3, and Ni-N4. (c) The corresponding fitting curves for Ni-N2 and Ni-N4. (d) XPS spectra of Ni 2p for Ni−N2, Ni−N3, and Ni−N4. (e) XPS spectra of N 1s for Ni−N2, Ni−N3, and Ni−N4. (f) Bader charge analysis reveals the net charge on Ni atoms in different Ni−N-x coordination environments. (g−i) Wavelet transform analysis of Ni K-edge EXAFS data in R-space for Ni−N2, Ni−N4, and Ni foil, obtained by using the Morlet wavelet function.
