Fe-Zeolite Functionality, Durability, and Deactivation Mechanisms in the Selective Catalytic Reductiompliance and dramatically reduce the harmful pollutants emitted from combustion engines. For stoichiometric exhaust, primarily from gasoline-powered vehicles, precious metals, or platinum-group metals (PGM), such as Pt, Pd, and Rh, have been the hallmark of three-way catalysis, e.g., [.–.], as they

Cu/Zeolite SCR Catalysts for Automotive Diesel NOx Emission Controlnia supported vanadia SCR catalysts, which have been successfully commercialized for stationary NOx emission control since the 1970s and installed on certain Heavy Duty Diesel (HDD) vehicles to meet the NOx emission regulations since the early 2000s, Cu/zeolite SCR catalysts exhibit higher NOx conve

Diesel Engine SCR Systems: Modeling, Measurements, and Controlficult to meet the tailpipe NO. and ammonia emission requirements primarily due to the complex SCR dynamics in engine transient operations. Closed-loop SCR urea dosing control is thus more preferable in order to achieve high SCR operational NO. conversion efficiency and low tailpipe ammonia slip. Ho
