WebThe low energy resolution of the Ce K-edge XANES spectrum of CeO 2 against the Cu K-edge XANES spectrum comes from the uncertainty of the core electron at the 1s level of two elements, which are 18.5 eV for Ce and 1.8 eV for Cu. 22 The energy bandwidths of the incident X-ray were about 4 eV for the Ce K-edge XANES region and 1 eV for the Cu K ... WebDec 13, 2013 · For the Cu–K edge data, only one concentration range has been considered, whereas two series of XAS spectra within two concentration ranges of added H 2 O 2 were acquired for the Fe–K edge. Details of the H 2 O 2 additions, with the relevant sample labels are indicated in Table 1.
