| Sumario: | Density functional theory calculations were performed to investigate propylene adsorption on the nonstoichiometric VSbO4(110) surface. V and Sb sites and two extreme ways of propylene approximation to the surface were considered. Among the six computed configurations, the most stable geometry corresponds to a parallel approach on the surface on a Sb site. This geometry makes possible a simultaneous adsorption of NH3 on a V site during the ammoxidation reaction to acrylonitrile. Sb(5s and 5p orbitals) interactions with C(2p) from double bond C=C were found, and no interactions with H atoms of CH3 and CH2 were produced. © 2015 American Chemical Society. |
