Characterization of vanadium oxide catalysts supported on γ-Al2O3 by 51V solid state n.m.r. spectroscopy
Abstract
51 V Solid state n.m.r. of V2O5/Al2O3 catalysts reveals two types of vanadia species on the surface: one due to a dispersed vanadia phase at lower vanadium contents and the other due to crystalline vanadia phase at higher vanadium content.
