a Atomic-resolution HAADF-STEM images of Pt/MAO catalysts, highlighting Pt single atoms (blue circles), clusters (yellow circles), and nanoparticles (white rectangles). b CO-DRIFTS spectra of Pt/MAO catalysts with varying Pt loadings. c Pt LIII-edge XANES spectra of 0.02Pt/MAO, 0.05Pt/MAO, and 0.15Pt/MAO, with bulk Pt foil and PtO2 as references. d Pt LIII-edge FT-EXAFS spectra of 0.02Pt/MAO, 0.05Pt/MAO, and 0.15Pt/MAO, with bulk Pt foil and PtO2 as references. e Wavelet transform of Pt LIII-edge EXAFS signals for 0.02Pt/MAO, 0.05Pt/MAO, and 0.15Pt/MAO.
