Abstract Redox transformations of vanadium species, deposited on the surface of a rutile monocrystal by annealing rutile with V2O5 were investigated by cyclic voltammetry. Two different vanadium species were observed at the surface: first, present in the crystal lattice of rutile, which undergoes the redox transformation V4+/V3+ only, and the second, present at the surface, which undergoes both the V5+/V4+ and V4+/V3+ redox transformations. The latter appears only when the subsurface layer becomes saturated with the former.
