(a) Pd K-edge normalized absorption spectra recorded for a 1 wt% Pd loaded catalyst supported on CeO2 (measurement in transmission in 5 s using the 2.8 T source and 12.5 s using the 1.7 T source). A zoom on the upper part is added. (b) Ce K-edge k2χ(k) EXAFS spectra recorded on a CeO2 pellet (measurement in transmission in 5 s). Dotted red lines correspond to measurements made with the 1.7 T bending magnet source and black lines to those made with the 2.8 T Superbend. |
