N2O Decomposition over Manganese Oxides

Nitrous Oxide Decomposition Over MCO3–Co3O4 (M = Ca, Sr, Ba) Catalysts

“…According to that classification, p-type oxides are the most active, n-type are the least, and insulators are intermediate. Based on these experimental observations a charge-transfer mechanism was suggested [54]. Similar mechanism is reported in the recent literature for direct nitrous oxide decomposition [24,34,55] as well as during its oscillation [56].…”

“…In addition, the E a values of all the catalysts were lower than that reported for Co/Ce catalyst [23]. The early reported results for N 2 O decomposition over metal oxides have correlated the activity with semi-conductivity of the catalysts [54]. According to that classification, p-type oxides are the most active, n-type are the least, and insulators are intermediate.…”

Effect of MnOx modification on the activity and adsorption of CuO/Ce0.67Zr0.33O2 catalyst for NO reduction

“…Moreover, Cu-Mn mixed oxides or MnO x itself exhibits favorable activity and selectivity for NO reduction by NH 3 or C 3 H 6 at low-temperatures [22][23][24][25][26], as well as for N 2 O decomposition and CO oxidation [27,28]. This property is beneficial because of the various types of labile oxygen available in the crystalline lattice of manganese oxide.…”

Optimization of Multicomponent Cobalt Spinel Catalyst for N2O Abatement from Nitric Acid Plant Tail Gases: Laboratory and Pilot Plant Studies

“…As a source of other nitrogen oxides in the stratosphere it also contributes to ozone layer depletion [2]. Due to its harmful impact on environment, catalytic decomposition of N 2 O received an increased attention during the past several years [3][4][5][6][7][8].…”
