低温用、耐水熱性、および耐被毒性のＳＣＲ触媒のためのレドックス活性カチオンのホストマトリックスとしてのＺｒＯｘ、Ｃｅ−ＺｒＯｘ、Ｃｅ−Ｚｒ−ＲＥＯｘ

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 characterized 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 characterized by high activity, hydrothermal durability and poison tolerance in the intended application.
