- W4080805 abstract "Adsorption of nitrogen at 77K has been studied on V2O5/MOx (M=Al, Ti) systems, used to oxidize hydrocarbons, obtained by impregnation of the supports with aqueous solutions of ammonium vanadate or by mechanical mixture of the oxides. The samples were doped with Na (0,1,3, or 6% weight) and calcined at 773K (to decompose the vanadium precursor) or 973K (to melt formed vanadia); characterization was performed by XRD and IR and V-UV spectroscopies. Incorporation of vanadium leads to a sharp decrease in the specific surface area, specially if sodium is simultaneously present. The specific surface area also decreases as the calcination temperature is increased in all samples, but not in Na-free alumina samples; in Na-rich alumina samples no effect of the calcination temperature on the specific surface area is observed. In the titania-supported samples the reaction is accompanied by a rutilisation of the support if Na and V are simultaneously present. The behaviour observed is discussed in terms of formation of stoichiometric and non stoichiometric Na-V-O, Na-Al-O, and Al-V-O compounds." @default.
