Abstract: A ruthenium water oxidation catalyst (WOC) bearing hydrophobic ligands was incorporated on the surface of a dye-sensitized nanostructured TiO2 film by formation of a host-guest adduct with the dye. This provides a new strategy for constructing photocatalytically active electrodes for water oxidation. The resultant photoanode exhibits a photocurrent of 800Acm(-2) under visible-light illumination (>400nm, 300mWcm(-2)) and 240Acm(-2) under simulated sunlight illumination (AM 1.5G, 100mWcm(-2)) with an applied bias of 0.2V vs. NHE in neutral phosphate buffer.
