Beschreibung
Zusammenfassung:	A method for the photocatalytically active coating of surfaces is presented and described, as well as an article (1) photocatalytically actively coated according to this method. The object of providing a method for the photocatalytically active coating of, in particular, metallic surfaces, whereby a permanently stable coating is produced without negatively affecting the photocatalytic activity of the layer, is achieved by a method, in which a substrate article is prepared which has a surface, a metallic adhesion-promoting layer is applied to the surface of the substrate article, a photocatalytically active layer consisting of one or more metal oxides is applied to the adhesion-promoting layer, wherein the metallic adhesion-promoting layer and the surface of the substrate article consist of a different material and the adhesion-promoting layer is selected such that it is not oxidized or reduced by the photocatalytically active layer.
