Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 4 Comparative (a) normalized Zn K-edge XANES spectra and (b) XAFS spectra of five Zn-containing samples: Zn foil, ZnO, ZnPc, Zn-CFs, and ZnNa-CFs. EXAFS fitting curves for (c and d) ZnNa-CFs and (e and f) Zn-CFs in R and k spaces, respectively. (g) WT contour plots of the five samples.
