Abstract:
A series of TiO2-ZrO2 Mixed oxide supported vanadia catalysts with various V2O5 loadings ranging from 1 to 16 wt % were prepared by a wet impregnation method and were characterized by means of solid-state V51 and H1 NMR spectroscopic techniques. The solid-state V51 NMR spectra of V2O5/TiO2-ZrO2 catalysts reveal the existence of two types of dispersed surface vanadium oxide complexes in a tetrahedral oxygen enviromnent at lower vanadium loadings and a third three-dimensional crystalline V2O5 in distorted octahedral environment at higher vanadium contents. The proton NMR results provide evidence for the existence of metal oxide support interaction through the support surface hydroxyl groups.
