Well ordered V2O3(0001) layers may be grown on Au(111) surfaces. These films are terminated by a layer of vanadyl groups which may be removed by irradiation with electrons, leading to a surface terminated by vanadium atoms. We present a study of methanol adsorption on vanadyl terminated and vanadium terminated surfaces as well as on weakly reduced surfaces with a limited density of vanadyl oxygen vacancies produced by electron irradiation. Different experimental methods and density functional… Expand

Atomic structure and special reactivity toward methanol oxidation of vanadia nanoclusters on TiO2(110).
It is obtained that the V4O6 nanoclusters can selectively convert methanol to formaldehyde at an unprecedented low temperature (300 K), and theoretical investigation indicates that on the surface of titania, vanadia mononuclear species, with oxidation states ranging from +2 to +4, can be strongly stabilized by aggregation into tetramers that are characterized by a charge transfer to the titania substrate.

Epitaxial Cubic Ce2O3 Films via Ce-CeO2 Interfacial Reaction.
This work proposes an alternative method for preparing ordered reduced ceria films based on the physical vapor deposition and interfacial reaction of Ce with CeO2 films, which yields bulk-truncated layers of cubic c-Ce2O3 which contain 25% of perfectly ordered vacancies in the surface and subsurface.

It is shown that the pure oxide surface stability can predict the surface segregation preference of the surface-confined mixed metal oxides, and that Fe is only stable on the surface under very high temperature and/or low-pressure conditions. Expand
