• nanostructure. It was reported that cathodic photocurrents were obtained at a nanocrystalline TiO2 film electrode due to oxygen reduction in alkaline solutions [7]. Visible light sensitization of TiO2 by surface complexation with [Fe(CN)6]4− has also been reported [8]. In such a case it was suggested that the
