a The schematic diagram of prepared Pd SA-doped SnO2 (SnO2/Pdatom) materials, b the low-resolution TEM image of the prepared SnO2/Pdatom samples and c, d the corresponding spherical-aberration TEM images at different areas, e the normalized XANES spectra at Pd K-edge (inset: expansion of the highlighted pink area) and f the transformed k-space curve and g the corresponding Fourier transformed k2-weighted χ(k) function of k2-weighted EXAFS spectra and h Wavelet transformation (WT) EXAFS for Pd foil, PdO reference and as-synthesized SnO2/Pdatom samples.
