Abstract

The invention relates to a semi-finished product for the production of catalysts, consisting of a metallic carrier and a coating of the carrier on its surface. The coating consists of particles of metallic powder anchored to the material of the carrier and to each other by sintering and contains pores. The invention also provides a method of producing a metallic carrier with a coating for the anchoring of the reactive oxide layer or of the catalytically acting material.
