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. Morphology and component analysis of NaBH4-R and C-FJH samples. (a) TEM image of the NaBH4-R sample. (b) HAADF image of the NaBH4-R sample and the corresponding EDX elemental mapping of Fe, O, and their overlapped images. (c) TEM image of C-FJH sample. (d) HAADF image of the C-FJH sample and the corresponding EDX elemental mapping of Fe, O, and their overlapped images. (e) Power generated during the C-FJH reaction and the corresponding real-time reaction phenomenon. (f) FT-EXAFS fitting curves of Fe foil, FeCl2, Fe2O3, NaBH4-R, and C-FJH samples in R space. (g) Fe K-edge XANES spectra of NaBH4-R and C-FJH samples. (h) XANES fitting valence of NaBH4-R and C-FJH samples.
