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. 6. Characterizations of Cu/SBA-15, Cu@Si/SBA-15, and Cs-Cu@Si/SBA-15. (a,b) Low-temperature (77 K) infrared transmission spectra. (c) FT k3-weighted Cu K-edge EXAFS spectra. (d–f) Wavelet transform for k3-weighted Cu K-edge EXAFS signals. Note: For all wavelet representations, the following set of parameters controls the WT resolution: σ = 1 and η = 7. Note that not all WT EXAFS are phase-corrected, which results in about 0.4 Å with respect to the actual radial distances.
