Ex situ Co K-edge FT-EXAFS of Co-TEG(0.25)/SiO2 calcined at different temperatures in comparison with that of Co(C2O4).2H2O as a reference Co compound which has a Co-COO bond. XAFS spectra were measured at ambient temperature; dried Co-TEG(0.25)/SiO2 (a), Co-TEG(0.25)/SiO2 calcined at 423 K (b), Co-TEG(0.25)/SiO2 calcined at 473 K (c) and Co(C2O4).2H2O (d).  [article HTML]
