Effects of humidity on the plasma-catalytic removal of low-concentration BTX in air

Conversion of dilute nitrous oxide (N2O) in N2 and N2–O2 mixtures by plasma and plasma-catalytic processes

“…1,3,[5][6][7][8] As a promising alternative to develop new catalysts, combination of catalysts with nonthermal plasma has been widely investigated in recent years for treatment of a variety of air contaminants such as volatile organic compounds (VOCs) and nitrogen oxides (NO x ). [9][10][11][12][13][14][15][16] The synergetic effects between plasma and catalysis include initiating chemical reactions at low temperature and improving products selectivity. [9][10][11][12][13][14][15][16] In fact, plasma and plasma-catalysis systems have also been investigated for decomposition of N 2 O, with nitrogen or argon as the background gas in most cases.…”

[17][18][19][20][21][22] These oxygen-free systems proved to be effective in decomposing N 2 O even at room temperature.…”

Study of Humidity Effect on Benzene Decomposition by the Dielectric Barrier Discharge Nonthermal Plasma Reactor

“…Xu et al [12] applied a NTP with CuO/AC catalyst for benzene removal, and they reported that the optimal RH was around 45%-60% for benzene decomposition. From these reported results, the influence of RH on VOCs removal efficiency may be enhancing [13] , suppressing [10,11,14] or balancing [15] , depending on the chemical structure of the VOCs. For clearing the effect and the mechanism of the RH on the VOC degradation, more experimental study is needed.…”

Removal of chlorobenzene using a sequential adsorption–plasma catalytic system over Ag‐, Ce‐ and Mn‐modified activated carbon catalysts

“…The results showed that all of the catalysts exhibited a good O 3 decomposition capacity in the initial NTP discharge period. For all the catalysts, O 3 generation increased with oxidization time, which was attributed to (i) the accumulation of organic intermediates over the active sites 33 and (ii) the reaction of excess atomic oxygen and molecular oxygen. 9 The Mn/AC catalyst exhibited the lowest amount of O 3 generation during the plasma oxidization time, suggesting that the Mn/AC catalyst was the most effective towards the decomposition of O 3 .…”
