Best-fitting results for Co K-edge k3[chi](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 k3[chi](k) and broken lines for FT-EXAFS.  [article HTML]
