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. High-resolution XPS spectra of (a) Ni 2p and (b) Fe 2p of NiFeOxHy/NF, Ni(OH)2/NF, and Ni(OH)2/NiFeOxHy/NF; XANES spectra of (c) Ni K-edge and (d) Fe K-edge, and the inset is the enlarged absorption edge; (e, f) the k3-weighted Fourier transformed EXAFS R-space patterns; continuously Cauchy wavelet transform k3-weighted EXAFS spectra of (g) Ni foil, (h) Ni(OH)2/NF, and (i) Ni(OH)2/NiFeOxHy/NF.
