A stable dye-sensitized photoelectrosynthesis cell mediated by a NiO overlayer for water oxidation.

ABSTRACT: In the development of photoelectrochemical cells for water splitting or CO₂ reduction, a major challenge is O₂ evolution at photoelectrodes that, in behavior, mimic photosystem II. At an appropriate semiconductor electrode, a water oxidation catalyst must be integrated with a visible light absorber in a stable half-cell configuration. Here, we describe an electrode consisting of a light absorber, an intermediate electron donor layer, and a water oxidation catalyst for sustained light driven water oxidation catalysis. In assembling the electrode on nanoparticle SnO₂/TiO₂ electrodes, a Ru(II) polypyridyl complex was used as the light absorber, NiO was deposited as an overlayer, and a Ru(II) 2,2'-bipyridine-6,6'-dicarboxylate complex as the water ox
