Abstract

Procedure for the preparation of catalysts containing platinum metal, characterized in that these catalysts are treated with tetravalent and hexavalent tellurium compounds containing 1 to 60% tellurium atoms (based on the amount of metallic Pt), in the presence of hydroxylammonium salts in an acidic medium and in the absence of reducing agents, especially hydrogen or formic acid.
