Abstract

The invention relates to a catalytically active, permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material can be used for separating mixtures of materials. The fact that various catalytically active substances can be incorporated into the material in various ways makes it highly flexible in terms of possible applications with properties which can be adapted to the particular purpose of an application. The inventive composite material can be used as a catalytically active membrane electrode, for example. According to the invention, the material is obtained by solidifying a suspension on and in a porous, permeable support. The production of the material requires either a very short period of heat treatment at temperatures of around 400.degree. C. or treatment for a longer period at very mild temperatures of below 100.degree. C.
