a Experimental Pt L-edge XANES and (b) Pt L-edge EXAFS spectra of PtSA@S-TFPT, PtO2, and Pt foil excluding phase correction. Fourier transforms of EXAFS spectra in (c) k-space and (d) R-space with their corresponding best fitting results for PtSA@S-TFPT excluding phase correction. e Schematic model and calculated bond lengths of PtSA@S-TFPT (top: front view, bottom: side view).
