title: Highly stable chemisorption of dyes with pyridyl anchors over TiO2: application in dye-sensitized photoelectrochemical water reduction in aqueous media.
abstract: A polypyridyl ruthenium sensitizer possessing pyridyl anchors (Ru-py) forms much stronger chemical linkages to TiO2surfaces compared to the conventional carboxylate and phosphonate ones. A highly stable dye-sensitized photoelectrochemical cell for water reduction is successfully demonstrated using this technique.
