Abstract: A structured layer arrangement includes a planar carrier substrate, on the functional-effective side of which a structured chromium layer is arranged. This includes chromium areas alternating with uncoated areas of the carrier substrate. Above the chromium layer, a two-dimensional reactive layer is arranged, which has a higher photocatalytic activity in partial areas above the chromium areas than in partial areas above the uncoated areas of the carrier substrate.

Abstract: A photocatalytic layer arrangement includes a carrier substrate on which a chromium layer with a defined nitrogen content is deposited. A titanium oxide layer having the formula TiOx (x=2-4) is grown on the chromium layer, and the anatase phase of the titanium oxide layer with respect to the rutile phase of the titanium oxide layer has a percentage in the range of 30%-90%.
