Gaseous Vanadium, Vanadium-Oxide and -Hydroxide Clusters: From Clusters to Model Catalysts

Beschreibung

The present work explores the reactivities of gaseous vanadium, vanadium-oxide, and oxovanadium-hydroxide clusters toward methanol and small hydrocarbons. Various means of mass-spectrometric techniques, isotopic labeling studies, infrared photodissociation spectroscopy, and complementary DFT-calculations are employed for this purpose. Additionally, the hydrogen-atom abstraction process from methane by polynuclear metal oxides is discussed. This work contributes to a better understanding of the metal-oxide cluster?s catalytic activity on a molecular scale.
