Abstract

Cu-SSZ-13 samples prepared by a novel one-pot synthesis method achieved excellent NH₃-SCR performance and high N₂ selectivity from 150 to 550 C after ion exchange treatments. The selected Cu_3.8-SSZ- 13 catalyst was highly resistant to large space velocity (800 000 h ^-1) and also maintained high NO_x conversion in the presence of CO₂, H₂O, and C₃H₆ in the simulated diesel exhaust. Isolated Cu²⁺ ions located in three different sites were responsible for its excellent NH₃-SCR activity. Primary results suggest that the one-pot synthesized Cu-SSZ-13 catalyst is a promising candidate as an NH₃-SCR catalyst for the NO_x abatement from diesel vehicles.
