Ex situ Co K-edge XANES (A) and FT-EXAFS (B) of Co(NO3)2.6H2O (a), impregnated Co/SiO2 (b) and impregnated Co-TEG(0.25)/SiO2 (c). Pattern-fitting results for impregnated Co/SiO2 and Co-TEG(0.25)/SiO2 using the XANES of Co(NO3)2.6H2O are illustrated by broken lines. The fitting quality (Rf) defined by equation (3)[link] is also indicated in this figure. XAFS spectra were measured at ambient temperature.  [article HTML]
