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. 3. (A) XANES spectra and (B) their corresponding Fourier-transformed (FT) k3-weighted spectra of the Pt K-edge of Pt foil, PtO2, Pt NWs, and PtNi NWs. (C) Pt K-edge EXAFS spectrum fitting of PtNi NWs at R space. WT plots for Pt element of (D) Pt foil, (E) PtNi NWs, and (F) Pt NWs. (G) Parameters of the best Pt K-edge EXAFS fitting results for Pt foil, PtNi NWs, and Pt NWs.
