Probing silica-supported Mo²⁺ by means of FT-IR of adsorbed CO

Abstract:

Well defined Mo2+ surface sites of silica-supported catalyst, produced by H2 reduction of the fixed molybdenum tetraallyl precursor, show a characteristic IR signal at 2170 cm -1 due to adsorbed carbon monoxide. Higher oxidation states of Mo in the same catalyst do not show any signal related to this probe molecule.
