Abstract

TiO2 (anatase) nanocrystals were prepared and their surface was modified by sol–gel deposition of vanadium oxide species. The resulting surface-modified TiO2 combines the good properties of both materials and new, synergistic properties arise, resulting in an increased electrical conductivity, voltage window, specific capacitance, and cycling stability.
