Abstract

In situ, temperature dependent, XAFS proved that Cr^II grafted on SiO₂ is extracted from the surface upon CO adsorption at 100 K: ΔR_Cr-O = +0.08 Å. CO adsorption evolves into two coverage dependent steps: (i) displacement of weak siloxane ligands (non-classical carbonyls); (ii) relaxation of R_Cr-O surface bond, R_Cr-CO optimization and transformation into classical carbonyls.
