Asset Details

  • Description:
  • XAS of Ptiso/TiO2 catalysts.a, XANES spectra collected at 200 °C immediately following various pretreatments (shown using solid lines). b, XANES spectra collected under CO oxidation reaction conditions (200 °C, 1% CO, 1% O2, balance He). Corresponding spectra following pretreatment are shown using dotted lines to emphasize changes induced by exposure to reaction conditions. The arrows show the change induced by exposure to CO oxidation conditions. c, EXAFS of catalysts after each pretreatment and under CO oxidation reaction conditions. The magnitude and imaginary portion of the Fourier transforms of the EXAFS spectra are shown using solid and dotted lines, respectively. Fits are shown in magenta. See also Supplementary Fig. 10 for EXAFS spectra.
