Abstract
The reactivity of rhenium (Re+) and rhenium monocarbonyl (ReCO+) catio ns in the gas phase toward CO oxidation by oxygen-containing reagents (NO, O-2, and N2O) was studied by ion cyclotron resonance. The presenc e of a carbonyl ligand significantly affects the ion reactivity. An ef fective route of metal monocarbonyl ion oxidation by molecular oxygen was found. This step can explain low-temperature activity of a number of oxide catalysts in the reaction of CO oxidation by molecular oxygen .
