Abstract

Eine selbstreinigende Oberfläche wird aus einer Metallmatrix gebildet, in die photokatalytisch aktive Titandioxid-Partikel eingelagert sind. Auch kann die photokatalytische Metallmatrix mit einem dünnen Metallfilm, der selbst keine Partikel enthält, überzogen sein, so dass die darunter liegenden Titandioxid-Partikel Poren bilden und damit ihre photokatalytische Aktivität beibehalten.A self-cleaning surface is formed from a metal matrix in which photocatalytically active titanium dioxide particles are embedded. Also, the photocatalytic metal matrix may be coated with a thin metal film which itself contains no particles, so that the underlying titanium dioxide particles form pores and thus retain their photocatalytic activity.
