Journal ArticleDOI
Effects of hydrothermal aging on NH3-SCR reaction over Cu/zeolites
TL;DR: In this article, the effects of hydrothermal treatment on model Cu/zeolite catalysts were investigated to better understand the nature of Cu species for the selective catalytic reduction of NO{sub x} by NH{sub 3}.
Journal ArticleDOI
Two different cationic positions in Cu-SSZ-13?
TL;DR: H(2)-TPR and FTIR were used to characterize the nature of the Cu ions present in the Cu-SSZ-13 zeolite at different ion exchange levels and results obtained are consistent with the presence of Cu ions at two distinct cationic positions in the SSZ- 13 framework.
Journal ArticleDOI
Thermal durability of Cu-CHA NH3-SCR catalysts for diesel NOx reduction
Steven J. Schmieg,Se H. Oh,Chang H. Kim,David B. Brown,Jong H. Lee,Charles H. F. Peden,Do Heui Kim,Do Heui Kim +7 more
TL;DR: In this paper, a commercial Cu-chabazite urea/NH3-SCR catalyst was assessed in a laboratory fixed-bed flow reactor system after differing degrees of hydrothermal aging.
Journal ArticleDOI
The Effect of Copper Loading on the Selective Catalytic Reduction of Nitric Oxide by Ammonia Over Cu-SSZ-13
TL;DR: The effect of Cu loading on selective catalytic reduction of NOx by NH3 was examined over a series of Cu ion-exchanged (20-80%) SSZ-13 zeolite catalysts.
Journal ArticleDOI
A common intermediate for N2 formation in enzymes and zeolites: side-on Cu-nitrosyl complexes.
Ja Hun Kwak,Jong H. Lee,Jong H. Lee,Sarah D. Burton,Andrew S. Lipton,Charles H. F. Peden,János Szanyi +6 more
TL;DR: Combined FTIR and NMR studies revealed the presence of a side-on nitrosyl species in the zeolite Cu-SSZ-13 that led to the proposal of a reaction mechanism that is fully consistent with the results of both kinetic and spectroscopic studies.
