Thermocatalytically active coating, substrate having the thermocatalytically active coating at least in parts, and process for producing same

A thermocatalytic coating for catalytic oxidation, said thermocatalytic coating consisting 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;

• wherein said catalytically effective amount is equivalent to not less than 2% by weight of lithium ions, based on total coating weight;
• 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;
• and
• 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.

A thermocatalytic coating for catalytic oxidation, said thermocatalytic coating consisting of an inorganic matrix and a catalytically effective amount of at least one lithium compound with catalytic activity for oxidation, said at least one lithium compound being incorporated in said inorganic matrix;

• wherein said inorganic matrix is a glass, glass solder or sol-gel matrix;
• wherein said inorganic matrix contains, in addition to said at least one lithium compound, at least one oxide ingredient selected from the group consisting of silicon oxide, titanium oxide, zirconium oxide, aluminum oxide, cerium oxide, iron oxide, tin oxide and boroxidic material;
• wherein said catalytically effective amount of said at least one lithium compound is equivalent to not less than 2% by weight of lithium ions, based on total coating weight;
• and
• 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.
