The structure of the surface VOx oxo complexes prepared by deposition from aqueous solutions on alumina in various modifications (γ, η, χ, θ, and δ) is studied using 51V and 1H NMR. The crystal structure and acidic properties of the surface of the starting phases of A12O3 do not substantially affect the structure of the surface VOx compounds. This is explained by the reconstruction of the surface layer of the support and a change in its acidic properties caused by the action of impregnating aqueous solutions.
