a High-resolution XPS spectra (S 2p) of h-ZIS, Pt3.0-ZIS, and Pt0.3-ZIS. b High-resolution XPS spectra (Pt 4f) of Pt/C, Pt3.0-ZIS, and Pt0.3-ZIS. c Fourier transform of k2-weighted Pt L3-edge of the EXAFS spectra for Pt foil, PtO2, Pt1.4-ZIS, and Pt3.0-ZIS. d Wavelet transform for the k2-weighted EXAFS spectra of Pt foil, PtO2, Pt1.4-ZIS, and Pt3.0-ZIS. R is the interatomic distance. FTIR spectra of CO adsorbed after the desorption processes for e h-ZIS, f Pt0.3-ZIS, and g Pt3.0-ZIS.
