Supported Ag Catalysts for the Lean Reduction of NO with C3H6
K. A. Bethke,Harold H. Kung +1 more
TL;DR: In this article, the activities of 2 and 6 wt% Ag/Al2O3 catalysts for lean NO reduction with C3H6 were compared, and the difference in the behavior of the two catalysts was attributed to the much higher Ag dispersion for the 2 wt % than the 6 Wt % sample, such that the oxidation states of Ag were different under reaction conditions.

Iron ion-exchanged zeolite: the most active catalyst at 473 K for selective reduction of nitrogen monoxide by ethene in oxidizing atmosphere
TL;DR: In this paper, the catalytic activity of iron ion-exchanged mordenite was investigated for selective reduction of nitrogen monoxide to nitrogen by ethene in the presence of oxygen at the temperature as low as 473 K. The effects of the zeolite structure are in the order of MOR > FER > MFI > Y > LTL.
