A review on the catalytic decomposition of NO to N₂ and O₂: catalysts and processes

Abstract

Recent advances in the catalytic decomposition of NO have been overviewed and divided into three categories: metal oxide catalysts (including perovskites and rare earth oxides), supported metal oxide catalysts (including alkali metals, cobalt oxide and noble metals) and Cu-ZSM-5.

Elucidating the effect of precursor decomposition time on the structural and optical properties of copper(i) nitride nanocubes

“…This is in accordance with other studies where oxidation of a primary amine to nitrile has occurred using a catalyst in a presence of oxygen. 31 Herein, we therefore suggest that CuO catalyzes the 33,34 however ultra-pure nitrogen gas is used. Herein, we therefore suggest that the N 2 gas feed is merely to maintain an inert atmosphere and is not reactive.…”

Observation and Rationalization of Nitrogen Oxidation Enabled Only by Coupled Plasma and Catalyst

“…7 Similar processes are at play in conventional combustion of fuel in air, motivating interest in NO decomposition catalysts for environmental protection. 8 However, catalytic N 2 oxidation under thermal conditions is unknown.…”

A Review on the Catalytic Decomposition of NO by Perovskite-Type Oxides

“…This decomposition reaction has highly negative Gibbs free energy (∆rGm = −86 kJ/mol), and the tendency of NO decomposition to generate N 2 and O 2 is large. Although it is thermodynamically feasible, the reaction needs to overcome the high activation energy of the reaction (~335 kJ/mol −1 ) [5,6]. Accordingly, NO can decompose smoothly under a catalyst and certain temperature conditions, and the development of greatly active and stable catalysts have always been a popular research direction and challenging task.…”
