Micro-structured, self-cleaning catalytically active surface

Abstract

The invention provides a microstructured, self-cleaning, catalytically active surface with elevations and depressions, comprising a catalytically active material in the depressions. The invention additionally provides a process for producing a microstructured, self-cleaning, catalytically active surface and a catalyst molding having such a surface in which a support surface is powder coated with particles having a size of from 0.05 to 200 μm and is subsequently coated with a catalytically active material. In a preferred embodiment of the process, (a) if desired, a base layer of metal is applied to a support surface by layer deposition from solution, (b) on the support surface or, if appropriate, on the surface of the base layer, a first layer of metal containing embedded particles with a size of from 0.05 to 200 μm is applied by layer deposition from a solution containing these particles in dispersed form, and (c) the first layer is coated with a catalytically active second layer.
