Sensitization of TiO2 by dyes: A way to extend the range of photocatalytic activity of TiO2 to the visible region

Abstract

The literature associated to the sensitization of TiO2 by modification with dyes is reviewed, including reactions leading to the transformation of dyes themselves, reactions of colorless pollutants, and hydrogen production, with emphasis on the involved mechanisms. The field of dye-sensitized solar cells is briefly addressed.
