Magnitude of FT-EXAFS (|k3χ|) as functions of the distance from a Pt atom of (a) Pt/Ti–FS and (b) H2O2-Pt/Ti–FS at different temperatures. (c) EXAFSs as functions of the distance from a Ti atom of A: Ti–FS at RT, B: Ti–FS at 500 °C, C: Ti–FS at RTc, D: H2O2–Ti–FS at RT, E: Pt/Ti–FS at RT, F: Pt/Ti–FS at 100 °C, G: Pt/Ti–FS at 250 °C, H: H2O2-Pt/Ti–FS at RT, I: H2O2-Pt/Ti–FS at 100 °C, J: H2O2-Pt/Ti–FS at 250 °C, and K anatase TiO2 at RT. For the Fourier transform, the EXAFS data in the k-range from 2.5 to 10.5 Å−1 and a Hanning window with a windowsill with of 0.5 Å−1 were used.
