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. Structure characterization of the optimal Co-OCB catalyst. (a) Aberration-corrected HAADF-STEM image, single Co atoms are highlighted by red circles. (b) Co-K-edge FT-EXAFS spectra for Co-OCB and reference samples. (c) Co-K-edge WT-EXAFS contour plots for Co-OCB and reference samples. (d) Co-K-edge FT-EXAFS fitting analyses for Co-OCB in R space and k space.
