“…The highest transforming charge is obtained with the MgO film thickness of 11.60 μm, which reaches 453 nC approximately. From figure 6(c), it can be seen that the emission spectrum mainly focuses on the second positive band of N 2 (C 3 ∏ u → B 3 ∏ g ) [27]. The highest emission intensity appeared at the wavelength of 357.8 nm.…”

“…[ 89,90 ] As shown in Figure 2, the factors affecting VOC degradation by DBD plasma can be summarized as reactor body (barrier dielectric material, electrode structure, and reactor structure), discharge conditions (power supply type, voltage amplitude, driving frequency, and gap width), gas‐phase parameters (initial concentration, VOCs type, and gas‐flow rate), and external factors (discharge gas atmosphere, humidity, and temperature). [ 91–96 ] In recent years, many experiments on VOC degradation have been carried out by using the DBD plasma reactor to study the effects of various factors on degradation efficiency and EE.…”

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.
