摘要： Catalysts and articles useful for selective catalytic reduction (SCR) are disclosed. The catalyst comprises a cerium oxide and an octahedral molecular sieve (OMS) comprising manganese oxide. The catalysts, which comprise 0.1 to 50 wt. % of cerium, can be made by doping, ion-exchange, deposition, or other techniques. Also disclosed is an SCR process in which a gaseous mixture comprising nitrogen oxides is selectively reduced in the presence of a reductant and the cerium-modified OMS catalyst. The cerium-modified manganese oxide OMS catalysts offer unexpected advantages for selective catalytic reduction, especially NH3-SCR, including improved thermal stability and improved activity for NOx conversion, especially at relatively low temperatures (100° C. to 250° C.).

摘要： An ammonia slip catalyst (ASC) comprising a first SCR catalyst, an oxidation catalyst comprising ruthenium or a Ru mixture, such as a Pt and Ru mixture, on a support comprising a rutile phase and a substrate is described. In some configurations, the ASC comprises a second oxidation catalyst. In other configurations, the ASC comprises a second oxidation catalyst and a third oxidation catalyst. The ASC's are useful for selective catalytic reduction (SCR) of NOx in exhaust gases and in reducing the amount of ammonia slip. Methods for producing such articles are described. Methods of using the ammonia slip catalyst in an SCR process, where the amount of ammonia slip is reduced, are also described.
