Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 2. (A) Mn K-edge XANES spectra of 0.8-Mn/Co3O4 along with those of Mn foil, MnO, and Mn2O3 as reference standards. (B) Fourier transformed EXAFS spectra of 0.8-Mn/Co3O4, Mn foil, MnO, and Mn2O3. (C) Corresponding WTs for the K3-weighted Mn K-edge EXAFS signals of 0.8-Mn/Co3O4, Mn foil, MnO, and Mn2O3. (D) Co K-edge XANES spectra of Co3O4 and 0.8-Mn/Co3O4 along with those of Co foil, CoO, and Co2O3 as reference standards. (E) Fourier transformed EXAFS spectra of Co3O4 and 0.8-Mn/Co3O4. (F) The schematically illustration of substitute CoOct by MnOct.
