In situ FTIR and Raman Study on the Distribution and Reactivity of Surface Vanadia Species in V2O5/CeO2 Catalysts
(Elsevier Science, 2015-07)
The surface structure and reactivity of vanadia supported on ceria catalysts were studied by Ramanspectroscopy and methanol adsorption and temperature-programmed surface reaction (TPRS) of theadsorbed species monitored in ...
ANTIMONY(V) OXIDE GRAFTED ONTO A SILICA-GEL SURFACE - ACIDIC PROPERTIES AND THERMAL-STABILITY
(Royal Soc ChemistryCambridgeInglaterra, 1992)
A DFT+u study, including the van der waals interaction, on the adsorption of XO2 molecules on the v2o5(001) surface (x= S, N, O, C)
(Elsevier Science, 2019-01)
Density functional theory (PBE+U), including the van der Waals interaction, has been used to study the adsorption of four triatomic molecules with two oxygen atoms in the ends, on the V2O5(001) surface. The most stable ...
