Change in the Co—O bond distances for Co/SiO2 (closed squares), Co-TEG(0.125)/SiO2 (open triangles) and Co-TEG(0.25)/SiO2 (open circles) during heat treatment in a flow of 20% O2/He. The Co—O bond distances were determined by curve-fitting analysis using Co K-edge FT-EXAFS illustrated in Figs. 4 ![]() ![]() |
