A Study of Spreading of Vanadia on Titania Polymorphs Using Mechanical Mixtures
(1993) The 10th International Congress on Catalysis 75. p.1755-1758- Abstract
- Mechanical mixtures of V2O5 and each of the three titania polymorphs TiO2(B), anatase and rutile were heated in air at 450°C. Spreading of vanadia was found to occur on all three polymorphs. After 36 hours of heating, coverage with interacting vanadia (the part that is insoluble in aq. NH3) on TiO2(B), anatase and rutile, respectively, was 54, 48 and 38 % of a theoretical monolayer. Raman spectra confirmed spreading and interaction. HREM images revealed no formation of multilayers of vanadia on titania. Use of the monolayer catalysts for toluene ammoxidation indicated their activity for benzonitrile formation to vary with respect to support in the order TiO2(B) > anatase > rutile.
