According to the invention, substrates comprising a photocatalytic layer containing Ti02 are produced using Ti02 particles which are optionally doped with metallic or non-metallic elements or compounds. In order to protect glass or plastic substrates, the photocatalytic layer has a concentration gradient of the Ti02 particles. Optionally, an organically modified, inorganic hybrid layer is provided between the substrate and the photocatalytic layer. |
