Photocatalytic H-2 evolution from neutral water with a molecular cobalt catalyst on a dye-sensitised TiO2 nanoparticle

We report on a self-assembled system comprising of a molecular H-2 production cobalt catalyst attached on a ruthenium dye-sensitised TiO2 nanoparticle. Visible light irradiation of the dispersed nanoparticles in the presence of the sacrificial electron donor triethanolamine produces H-2 photocatalytically in pH neutral water and at room temperature.
