UNITARY COMPOSITE STRUCTURE EXHIBITING CATALYTIC ACTIVITY, SINTERIZED POROUS COMPOSITE STRUCTURE EXHIBITING CATALYTIC ACTIVITY AND PROCESS OF PREPARING THE UNIT COMPOSITE STRUCTURE

摘要

This invention is directed to the preparation of articles exhibiting catalytic activity and, in particular, to articles which are exceptionally suitable for catalytically converting gases from organically fueled power plants, internal combustion engines, and other fluid and gaseous catalysis. The inventive articles comprise a unitary composite structure consisting essentially of a catalytically active precious metal and/or a base metal which, the base metals in particular, become catalytically active upon oxidation. The catalysts are integrally combined with a supporting porous sintered structure of metal or ceramic.
