Solid-state vanadium-51 NMR studies of supported V{sub 2}O{sub 5}-WO{sub 3}/TiO{sub 2} catalysts
Abstract
Solid-state wide-line vanadium-51 NMR spectra of supported V{sub 2}O{sub 5}-WO{sub 3}/TiO{sub 2} catalysts were obtained under ambient conditions. A distorted tetrahedral vanadium unit is favored at low vanadia loadings in the absence of tungsten oxide. Generally, addition of tungsten oxide to low loadings of vanadia supported on titania promotes the formation of a distorted octahedral vanadium species, while a distorted tetrahedral vanadium unit is also present. A distorted octahedral vanadium unit is favored on the surface at high vanadia loadings in both the presence and absence of tungsten oxide.
