“…The increased CO 2 selectivity was due to the further oxidation of CO and organic intermediates (such as methanol, phenol, and 3-nitrophenol). Jiang et al [93] 1. No matter what Mn-based catalysts are used, the VOCs oxidation and energy efficiency in the PPC system are higher than that of the NTP system.…”

“…In order to obtain further insights into this phenomenon, the underlying mechanisms that result in this synergistic effect need to be elucidated. A large number of experimental studies have been focused on VOCs removal efficiency over different catalysts [43,47,88,93,95]. Nevertheless, not so many studies actually focus on the mechanism of VOCs degradation in the PPC system [45,46].…”

The combination of non-thermal plasma (NTP) and catalyst characterized by high energy efficiency, enhanced volatile organic compounds (VOCs) removal efficiency, high product selectivity, and low production of unwanted and/or toxic by-products possesses a great promise for the abatement of VOCs. This work reviews the state of knowledge regarding Mn-based catalysts for VOCs abatement in the post-plasma-catalytic (PPC) system. First, the development and the performance of different Mn-based catalysts such as pure manganese oxide, mixed manganese oxide-based catalysts, and supported Mn-based catalysts in terms of VOCs abatement and O 3 decomposition are summarized. Then, the mechanism of the VOCs decomposition in the NTP and PPC system is discussed. Finally, the modeling and simulation of VOCs abatement in the NTP and PPC system are overviewed. This review aims at providing a reference guide for the development and optimization of VOCs abatement in the PPC system using Mn-based catalysts.

“…The synergistic degradation of VOCs by plasma and catalyst can combine their advantages to effectively improve VOCs' degradation efficiency, EE, CO 2 selectivity, and reduce toxic byproducts. [ 117–120 ] The term “synergy” should be understood as the surplus effect of both technologies but is not the simple sum of their individual effects. [ 121 ] The synergistic effect of catalyst and plasma can be attributed to the following reasons [ 120,122–125 ] : the catalyst can reduce the activation energy of oxidation reaction in the degradation process and accelerate the reaction process; catalysts can improve the decomposition rate of ozone generated in discharge, produce O · and other active species, and promote the deep oxidation of plasma products.…”

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.

“…Therefore, the NS-DBD actuators can be applied in plasma etching [1], coating [2], biology medicine [3], gas conversion [4], aerodynamics [5] and combustion [6]. In particular, the volatile organic compounds (VOCs) degradation by the DBD plasma actuators has been intensively investigated, and it has shown that the method has potential application in air-cleaning systems for the benzene removal [7], toluene, and xylene destruction [8,9,10]. The plasma–surface interactions, such as the emission of secondary electrons and the charging of the electrons and ions, are very crucial to the etching, coating, and biology medicine applications.…”

Numerical Investigation on the Effects of Dielectric Barrier on a Nanosecond Pulsed Surface Dielectric Barrier Discharge

et al. 2019

In order to understand the impacts of dielectric barrier on the discharge characteristics of a nanosecond pulsed surface dielectric barrier discharge (NS-DBD), the effects of dielectric constant and dielectric barrier thickness are numerically investigated by using a three-equation drift–diffusion model with a 4-species 4-reaction air chemistry. When the dielectric constant increases, while the dielectric barrier thickness is fixed, the streamer propagation speed (V), the maximum streamer length (L), the discharge energy (QD_ei), and the gas heating (QGH) of a pulse increase, but the plasma sheath thickness (h), the fast gas heating efficiency η, and the charge densities on the wall surface decrease. When the dielectric barrier thickness increases, while the dielectric constant is fixed, V, L, QD_ei, and QGH of a pulse decrease, but h, η, and the charge densities on the wall surface increase. It can be concluded that the increase of the dielectric constant or the decrease of the dielectric barrier thickness results in the increase of the capacitance of the dielectric barrier, which enhances the discharge intensity. Increasing the dielectric constant and thinning the dielectric barrier layer improve the performance of the NS-DBD actuators.
