LEIS has been used to study the surface structure of V205/γ-Al2O3 catalysts as a function of V-loading. At low loadings (< 7 wt%) the vanadium species is optimally dispersed over the support, while at medium loadings (< 11 wt%) multilayered structures are formed. Three-dimensional models for the surface structures are proposed.
