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 2. XAS analysis of Cu/Ni−NC. (a) XANES spectra of the Ni K-edge. (b) XANES spectra of the Ni K-edge. The peak circled indicates the presence of Ni−Cu bonds. (c) FTs of κ3-weighted Cu K-edge EXAFS data. (d) FTs of κ3-weighted Cu K-edge EXAFS data. (e,f) Experimental and fitting EXAFS curves of Cu/Ni−NC in R space; the measured and calculated spectra show excellent agreement. (g) Wavelet transform (WT) for the κ3-weighted Ni and Cu K-edge EXAFS signals.
