Claims15
A method of cleaning a surface comprising cleaning the surface by:
- (1) coating said surface with a composition comprising a photocatalyst selected from the group consisting of titania and zinc oxide and a ruthenium bi- or ter-pyridyl or phenanthroline-based sensitizer, and (2) exposing the surface to visible or infra-red light.
A method of cleaning a surface comprising cleaning the surface by depositing a dry functional residue on a surface, said residue deposited from a composition, said composition comprising a photocatalyst selected from titania and zinc oxide, wherein the photocatalyst is sensitised by a ruthenium bi- or ter-pyridyl or phenanthroline-based sensitiser and said sensitiser causes activation by visible or infra-red light.
