Figure 3. Atomic structure characterization and theoretical calculations. a) Pt L3-edge XANES spectra and b) FT-EXAFS spectra of Pt foil, PtO2, and NP-Pt3. Corresponding wavelet transform (WT) of the k3-weighted EXAFS data of c) Pt foil and d) NP-Pt3. Atomic configuration and the adsorption site of H*, e1) Pt-top model, e2) Pt3Ni-hollow model, e3) Pt3Ni-top model, e4) Pt3(FeCoNi)-hollow model. f) Calculated free-energy changes in different models. g) Calculated DOS of the Pt, Pt3Ni, and Pt3(FeCoNi) models.
