Abstract

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