“…There have been extensive studies on the degradation of VOCs by NTP since the late 1990s and early 2000 [10]. Many types of plasma reactors can be used to generate NTP such as corona discharge [11], dielectric barrier discharge (DBD) [12], and ferroelectric pellet packed-bed reactor [13,14]. Compared with other discharges, DBD is a most used NTP owing to its high-energy electron density and better discharge uniformity.…”

Volatile organic compounds (VOCs) such as benzene (C 6 H 6 ), methylbenzene (C 6 H 5 CH 3 ), dichloromethane (CH 2 Cl 2 ) and methyl ethyl ketone (CH 3 COCH 2 CH 3 ), are exhausted into the atmosphere from a variety of industrial processes [1]. The removals of these VOCs are required because they are responsible for many environmental problems and diseases such as ozone depletion, photochemical smog, heart disease, asthma and even cancer [1][2][3][4]. There exist a lot of traditional techniques for VOCs degradation, including adsorption, incineration and condensation [5][6][7][8]. These methods have

“…Subsequently, the recombination of •CH 3 and the oxygen species via several steps (Reactions (9)–(13)) can form CH 3 O 2 •, CH 3 O• and HCHO. The latter is further oxidized to HCO• by •OH or divided into CO and H (Reactions (14) and (15)) [ 38 ]. Additionally, HCO• is also the precursor of the CO and CO 2 , according to Reactions (16–19).…”

The removal of acetone and benzene series (BTEX) under individual and concurrent conditions is carried out in a coaxial nonthermal plasma (NTP) reactor. The results show that the benzene series has a significant negative impact on acetone conversion and CO2 selectivity under NTP treatment. Furthermore, it is found that p-xylene significantly promotes COx selectivity under co-treatment with acetone because of greater CO generation. Based on the results of transient FTIR, MS, and GC-MS, it is seen that quantities of formic acid, formaldehyde, and ring-opening byproducts from benzene series decomposition are reduced, while quantities of aromatic byproducts with carboxyl, phenolic, and aldehyde groups on the benzene ring increase under coexistence conditions. With the help of theoretical calculation and kinetic analysis, hydrogen abstraction from the methyl group and active hydroxyl radical consumption are proposed as critical factors in the BTEX inhibition effect on acetone degradation.

“…The results explored that when the O 2 concentration was 0.3%, the promotion effect on the degradation of the two VOCs was the most obvious. Sugasawa et al [ 107 ] discussed the effect of water on the degradation of dichloromethane, toluene, and methanol using N 2 as the carrier gas. The results showed that water could promote CO 2 selectivity and carbon balance in varying degrees.…”

On the basis of plasma technology, the progress of the volatile organic compounds' (VOCs') degradation by low‐temperature plasma alone is discussed first, including reactor types, influencing factors of plasma degradation of VOCs and the reaction mechanism between plasma and VOCs. Then, the research status of three VOC degradation technologies (catalysis, adsorption, and biotechnology) and their synergistic degradation of VOCs with plasma are reviewed, including the effect of catalyst position on VOC degradation, the interaction mechanism between plasma and catalyst; the factors affecting the adsorption of VOCs by carbon‐based adsorbents and zeolite, the degradation of VOCs by plasma‐assisted adsorbent; the features of different biological systems, the influencing factors of VOC degradation by the biotrickling system, and the degradation of VOCs by plasma‐assisted biotreatment. Finally, the prospects of developments in high‐tech based on plasma are discussed.
