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. Chemical state and coordination structure of P-EP. (a) XPS survey spectra, (b) Ni 2p XPS spectra, and (c) C 1s XPS spectra of Ni/ C, P-EP, and cycled P-EP. (d) XANES spectra at the Ni K-edge. (e) XANES spectra at the Ni K-edge with partial area enlargement. (f) FTs of Ni K-edge EXAFS data. Wavelet transform (WT) contour plots of EXAFS for (g) P-EP, (h) Ni/C, (i) Ni foil, and (j) NiO.
