TLDR
In this article, the authors used Co/Al catalysts containing oxides of alkali metals (Li, Na, Rb, Cs) as additive to catalyzed process.Abstract:
The process was carried out over Co/Al catalysts containing oxides of alkali metals (Li, Na, Rb, Cs) as additives. The presence of alkali metals generally decreases the activity of the Co/Al catalysts, except for very low concentrations of Li, Na, Rb and Cs atoms. Activity of catalyst increases with atomic weight of alkali metal additive. Possible effect of additive on catalyst structure is briefly discussed with respect to catalyzed process.read more

The catalytic reduction of nitric oxide over supported ruthenium catalysts
TL;DR: In this paper, the authors examined the performance of supported ruthenium catalysts for reducing NO to N2 in an exhaust-like feedstream and found that the rate and temperature of NO removal is largely dependent on the NO inlet concentration and independent of the concentration of reducing agents in the system.

The catalytic chemistry of nitric oxide: I. The effect of water on the reduction of nitric oxide over supported chromium and iron oxides
TL;DR: The reduction of NO with CO over alumina supported iron oxide and chromium oxide is a relatively fast process as mentioned in this paper, although this was shown to be due to inhibition by H 2 O, which is a primary product of the NOH 2 reaction.
