ABSTRACT:
A method of making a photoactive coating includes depositing a first coating material containing zirconium oxide over at least a portion of a substrate and depositing a second coating material containing titanium oxide over at least a portion of the first coating material to provide a coated substrate. At least one of the first and second coating materials is deposited by pyrolytic deposition.
