ZROX, CE-ZROX, CE-ZR-REOX AS HOST MATRICES FOR REDOX ACTIVE CATIONS FOR LOW TEMPERATURE, HYDROTHERMALLY DURABLE AND POISON RESISTANT SCR CATALYSTS

摘要

The present invention relates to application of catalysts for the Selective Catalytic Reduction of oxides of Nitrogen using N-containing reductant. The catalysts are characterised as phase pure lattice oxide materials into which catalytically active cations are incorporated at high levels of dispersion such that conventional analysis reveals a highly phase pure material. The materials are further characterised by high activity, hydrothermal durability and poison tolerance in the intended application.
