Abstract

Single crystals of TiO~2~ and SrTiO~3~ are sensitized by thin films of a ruthenium surfactant dye, which is able to sustain catalytic oxidation of water upon irradiation with visible light. Calculated turnover numbers exceed 2000. Doping of the crystals with niobium does not improve the suitability of these semiconductors as photoanodes, contrary to results obtained with polycrystalline Nb‐doped TiO~2~.
