FT k³-weighted EXAFS spectra of (a) Pt/CeO₂, (b) Rh/CeO₂, and (c) Ru/CeO₂ together with the corresponding reference oxide and foil (without phase correction), (d–g) C_s HAADF-STEM micrograph of Pt/CeO₂, (h) 3D map of the z-contrast of close-up view of (g) and (i) EXAFS free parameters obtained from fitting. The values in parentheses are errors from fitting. R, σ², E₀ and r represent the radial distance, Debye–Waller factor, energy shift and goodness of fit, respectively.
