Photocatalytic H2 evolution from neutral water with a molecular cobalt catalyst on a dye-sensitised TiO2 nanoparticle

Abstract

We report on a self-assembled system comprising of a molecular H(2) production cobalt catalyst attached on a ruthenium dye-sensitised TiO(2) 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.
