TLDR
In this article, a Co/Al catalyst containing potassium oxide as an additive was used to reduce NO with hydrogen using a differential reactor operated at atmospheric pressure, and the process was carried out over a co-al catalyst with potassium oxide, which generally produces a decrease in activity of the Co/al catalyst except for very low concentrations of potassium atoms.Abstract:
Catalytic reduction of NO with hydrogen has been studied using a differential reactor operated at atmospheric pressure. The process was carried out over a Co/Al catalyst containing potassium oxide as an additive. The presence of potassium generally produces a decrease in activity of the Co/Al catalyst except for very low concentrations of potassium atoms.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.
