Description
Summary:TiO2 photoelectrodes modified with organic dyes with pyridine anchoring groups are prepared, which are used as photoanodes of dye-sensitized photoelectrochemical cells for efficient water reduction with high photocurrent density and stability in aqueous solutions. Vigorous H2 generation with a production rate of around 250 μmol h−1 is realized with a photoanode of an active area of 5 × 5 cm2.
