(a) Imaginary part and magnitude of Fourier transform (𝑘³-weighted, 4.0<𝑘<15Å⁻¹, Pt-Pt phase and amplitude corrected) of experimental EXAFS data at Pt edge for Pt/γ-Al₂O₃ (black line) and Pt-Pd/γ-Al₂O₃ (red line). (b) Imaginary part and magnitude of Fourier transform (𝑘³-weighted, 4.0<𝑘<13Å⁻¹, Pd-Pd phase and amplitude corrected) of experimental EXAFS data at Pd edge for Pd/γ-Al₂O₃ (black line) and Pt-Pd/γ-Al₂O₃ (red line).
