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 3. (a) Co 2p XPS spectra of reduced CoZr and CoInZr-0.7 catalysts, (b,c) normalized Co K-edge XANES spectra and partial enlarged views, (d) k3-weighted FT magnitudes of Co K-edge EXAFS spectra (k3 χ(k)), and (e) wavelet transforms for the k3-weighted EXAFS data of CoZr and CoInZr-0.7. (Reduction conditions: 300 °C and 50 mL min−1 H2 flow for 1 h.)
