Patent ID: 8008225

Claim:
A coated substrate comprising a substrate and a thermocatalytically active coating, wherein said thermocatalytically active coating is applied to at least a part of the substrate and consists of a sol-gel layer and a catalytically effective amount of at least one lithium compound with catalytic activity for oxidation embedded in the sol-gel layer in an amount equivalent to not less than 2% by weight of lithium ions, based on total coating weight; wherein said at least one lithium compound is selected from the group consisting of lithium halides, lithium phosphate, lithium nitrate, lithium sulfate, lithium acetate, lithium propionate, lithium citrate tetrahydrate and lithium derivatives of carboxylic acids; and wherein said sol-gel layer comprises a network of at least one oxide ingredient selected from the group consisting of silicon oxide, germanium oxide, titanium oxide, zirconium oxide, aluminum oxide, cerium oxide, boron oxide, iron oxide and tin oxide.
