Highly stable chemisorption of dyes with pyridyl anchors over TiO2: application in dye-sensitized photoelectrochemical water reduction in aqueous media

Highly stable chemisorption of dyes with pyridyl anchors over TiO2: application in dye-sensitized photoelectrochemical water reduction in aqueous media

A polypyridyl ruthenium sensitizer possessing pyridyl anchors (Ru-py) forms much stronger chemical linkages to TiO2 surfaces compared to the conventional carboxylate and phosphonate ones. A highly stable dye-sensitized photoelectrochemical cell for water reduction is successfully demonstrated using...

Zusammenfassung:A polypyridyl ruthenium sensitizer possessing pyridyl anchors (Ru-py) forms much stronger chemical linkages to TiO2 surfaces compared to the conventional carboxylate and phosphonate ones. A highly stable dye-sensitized photoelectrochemical cell for water reduction is successfully demonstrated using this technique.
