Hydrogen Photo-production from Ethanol and Water over Au/TiO2 Rutile Single Crystal

Gold supported on a commercial anatase: rutile mixture has been found to be 3 times more active for hydrogen production than the previously reported gold on anatase photocatalysts. Other products detected were ethene and acetaldehyde; these products were enhanced in the presence of water. In-situ EPR spectroscopy was used to show that the gold nanoparticles act as sinks for electrons produced in the conduction band of the titania. Experiments with gold supported on Brookite showed that this support was comparable in activity with anatase, although a Brookite: anatase mixed phase support gave higher activity than either pure Brookite or pure anatase.
