A review of the selective reduction of NOx, with hydrocarbons under lean-burn conditions with non-zeolitic oxide and platinum group metal catalysts
TL;DR: In this paper, it is concluded that although there is indirect, mainly spectroscopic, evidence for various reaction intermediates on the catalyst surface, it is difficult to confirm that any of these are involved in a critical mechanistic step because of a lack of a direct quantitative correlation between infrared and kinetic measurements.

The mechanism for NOx storage
TL;DR: In this paper, the mechanisms for storing NOx in platinum-barium-alumina catalysts during lean-rich transients are investigated, and NO2 is found to be important for oxidation of the catalyst or of nitrites to form nitrates.

Mechanism of the selective reduction of nitrogen monoxide on platinum-based catalysts in the presence of excess oxygen
TL;DR: A range of alumina-supported platinum catalysts have been prepared and investigated for the selective reduction of nitrogen monoxide in the presence of a large excess of oxygen in steady state microreactor experiments.

Methane combustion over palladium catalysts: The effect of carbon dioxide and water on activity
TL;DR: In this article, the influence of water and carbon dioxide on the activity of a series of palladium catalysts for the combustion of methane has been studied and it was concluded that both water and CO 2 poison the same active sites on the palladium oxide with water able to displace carbon dioxide to form an inactive surface hydroxide.

Role of oxygen in selective reduction of nitrogen monoxide by propane over zeolite and alumina-based catalysts
TL;DR: The role of coexisting oxygen in the selective reduction of nitrogen monoxide by propane on H-zeolites, alumina, Cu-ZSM-5 zeolite and Pt/Al2O3 catalysts was investigated in this paper.
