Methanol oxidation in dry and humid air by dielectric barrier discharge plasma combined with MnO2–CuO based catalysts

“…Two electrodes (one copper comb and one copper plate stuck on the glass plate) were separated from each other by a 2 mm thick glass plate acting as a dielectric barrier. Details of the reactor and experimental setup can be found in [22]. 4g of catalyst were placed in the post discharge (PP) area in a 1.6 cm inner diameter glass tube.…”

“…The section detailing the catalyst preparation can be found in [22]. Briefly, a solution of Mn(NO3)2.4H2O was mixed with 2 mm alumina balls and stirred for 4 hours in a rotary evaporator under reduced pressure.…”

“…Sivachandiran et al [8] reported a very detailed study on the effect of humidity on isopropanol adsorption on TiO2 surface and its ensuing non thermal plasma treatment. They This work is in the continuity of a study started on methanol elimination by non thermal plasma combined to catalysis at atmospheric pressure, in dry air conditions [22]. The effect of humidity on the methanol conversion, by products selectivities and ozone concentration is investigated.…”

The Pivotal Role of Catalysis in France: Selected Examples of Recent Advances and Future Prospects.

“…However, they generate ozone and NO x , which must be eliminated and so requires post‐treatment by filtration and/or catalytic decomposition of the exhausts . For good efficiency, such system should be placed downstream of the plasma discharge (post‐plasma catalytic or PPC system) as illustrated in the case of trichloroethylene abatement on Pd/LaMnO 3 or of methanol oxidation on Mn, Ce, and Cu oxides supported on γ‐Al 2 O 3 . The synergetic association of the plasma technology with a photocatalytic pathway is also of particular interest, as proposed in recent studies on ethanol abatement in air on MnO x /TiO 2 catalysts or on the elimination, on a TiO 2 supported on glass fiber material, of isovaleraldehyde, a molecule present in the exhaust gases from animal quartering centers …”

Oxidation of propene from air by atmospheric plasma-catalytic hybrid system

“…However, NTP technology for indoor air treatment has the disadvantage, because it produces the undesirable by-products such as ozone, aldehyde, and NO x . [4][5][6] To overcome the by-products formation and to increase the energy efficiency, NTP could take the advantage of its synergetic effect through the combination with heterogeneous catalysts. This combination can be either single-stage (in-plasma catalysis) or two stages (postplasma catalysis).…”
