Post-plasma catalytic removal of methanol over Mn–Ce catalysts in an atmospheric dielectric barrier discharge

Non thermal plasma assisted catalysis of methanol oxidation on Mn, Ce and Cu oxides supported on γ-Al2O3

“…Within the different reported mechanisms, the most recent studies on CuO mixed oxides implied that the improved reactivity towards methanol conversion and ozone abatement is due to reactions occurring at the interphase of the CuO with MnO 2 [25,[62][63][64][65].…”

“…It was also demonstrated that the presence of a catalyst within a plasma discharge resulted in a synergistic effect and was improving VOCs and by-products conversion. Various publications and reviews give detailed reports on non thermal plasma (NTP) coupled to catalysis on VOCs removal such as trichloroethylene [8,[11][12][13], benzene [8,[14][15][16], toluene [8,17,18], isopropanol [19][20][21] and methanol [22][23][24][25]. In particular, a significant attention has been brought on manganese oxide based catalysts, owing to their capacities to store oxygen and activate ozone [11,16,17,19,[25][26].…”

Effects of oxygen-containing functional groups on the synergy effect in pulsed bipolar plasma-catalytic reactions of volatile organic compounds

“…7 The discharge strength and active species yield of bipolar pulses are greater than those of AC and DC. 8 Several studies have applied plasma catalysis to remove VOCs using supported metals, [9][10][11] metal oxides, [12][13][14] supported metal-metal, 15 metal-metal oxides, 16,17 or perovskite-type [18][19][20] catalysts. Perovskite oxide has a crystal structure similar to that of calcium titanate (CaTiO 3 ).…”

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

“…Such a combination helps to bring down the disadvantages of both catalytic and plasma treatments. 7,8 In this study, the dielectric-barrier discharge (DBD) reactor, combined to 1 wt.% of Pd/Al 2 O 3 beads catalyst, were investigated for the removal of propene from air at the atmospheric pressure. Reported results, as a function of the gas temperature and the input plasma energy density, consider the catalyst effect, the plasma effect and the plasma-catalyst effect on the efficiency of propene conversion.…”
