Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 3 Characterization of material properties. (a) Normalized XANES spectra recorded at the Fe K-edge of BF, B1.02F, and B1.02F-CC; (b) an enlarged view of the absorption edge region marked by the dashed rectangle in (a); (c) Arrhenius-type plots of the electrical conductivity for BF, B1.02F, and B1.02F-CC. The plot is presented in this form for direct readability of the conductivity values. Note that the activation energy should be obtained from the linear fit of log(sT) versus 1000/T (not shown); (d) TGA curves of BF, B1.02F, and B1.02F-CC measured from 200 to 800 °C.
