Quantum chemical simulation of propylene oxidation on Ag20

详细

The adsorption of atomic oxygen and the mechanism of propylene (C₃H₆) oxidation to oxide (C₃H₆O) on an Ag₂₀ tetrahedral cluster were studied using density functional theory. The effects of cluster structure and active site structure on the mechanism of this reaction were considered. The oxidation of C₃H₆ can occur both on an edge and at the apex of the silver cluster. The C₃H₆O formation steps on the cluster edge are characterized by lower activation energies.
