Abstract

A substrate, such as a glass, glass ceramic, ceramic or metal substrate, is provided with a thermocatalytically active coating on at least a part of the substrate surface. The thermocatalytic coating contains an inorganic lithium salt or organic lithium-containing compound in an amount that is equivalent to not less than 2 wt. % of lithium ions, based on total coating weight. The thermocatalytic coating has a glass, glass solder or sol-gel matrix in which the lithium salt or organic lithium-containing compound is introduced. Optional barrier and IR-reflecting layers are arranged between the substrate surface and the thermocatalytically active coating.
