Figure 8
Best-fitting results for Co K-edge k3χ(k) and FT-EXAFS of Co-TEG(0.25)/SiO2 calcined at 423 K (a, b) and 473 K (c, d), indicating the formation of small oxide clusters in the calcined samples. Curve-fitting analysis was carried out using the Co–O and Co–Co coordination shells. Fitting results are represented by open squares for k3χ(k) and broken lines for FT-EXAFS.
