Figure 7
An Fe Kα XRF map of the same area of the ceria-supported platinum catalysts under: (a) room temperature in an inert gas flow, (b) reducing conditions at 300°C and (c) re-oxidizing conditions at 500°C. XANES mapping was carried out on each area with the CA performed in MANTiS, grouping the pixels according to their spectroscopic variance shown on the right. (d) Individual XANES spectra extracted from selected CA on the samples in (a), (b) and (c), compared with the XANES spectra of two Pt standards: PtO₂ and Pt foil.
