“…Similar results were presented by Zhang et al and Hegeler et al, who found that the positive corona discharge produces around 2–6 times more ozone in comparison with the negative corona. Many researches showed that a brilliant and uniform streamer corona occurs in the reactor of positive DC, which, the glow corona was observed for negative DC. , Since the electric field strength in the discharge gap is sufficient to generate streamers, it should be also adequate for the electrons to gain the energy required for dissociation of O 2 molecules to synthesis ozone molecules. − …”

A coaxial nonthermal plasma (NTP) reactor was used for the removal of nitric oxide in mist. The effects of discharge gap, thorn number, tooth slice number as well as discharge polarity on NO oxidation and NO x removal were investigated. Decreasing the discharge gap is favorable for the NO oxidation and NO x removal. The mist is almost captured completely even under a relative low input energy. Increasing the thorn number of discharge slice or tooth slice number facilitates the energy input in the plasma reactor and thus enhances the NO oxidation and NO x removal under a fixed applied voltage. The energy efficiency for the positive DC (4.5 g NO/kWh) is three times as much as that for the negative DC (1.5 g NO/kWh), corresponding to NO oxidation efficiency of around 80%.

“…The degradation of the benzene series in each reactor was investigated, and the operating parameters of the reactor were optimized by power supply matching, structural design, and condition control. [ 79,80 ] The parameters for characterizing the degradation effect of VOCs include removal efficiency (RE), EE, and CO 2 selectivity

(S_{C {normalO}_{2}})

. Before defining these parameters, it is necessary to define the specific input energy (SIE) that characterizes the energy distribution in the discharge area in unit gas volume, as shown in the following formula:

normalS normalI normalE = \frac{P}{Q} \times 60,

where SIE has the unit of J/L, P is the discharge power (W), Q is the gas‐flow rate (L/min).…”

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.

The discharge mode and photoelectric characteristics of Ar/NH3 DBD (dielectric barrier discharge) are studied to discuss the stability of the discharge under the influence of Penning ionization and attachment reaction. There are three discharge modes, including stable uniform glow discharge, unstable glow discharge and unstable columnar discharge. Discharge instability, including nonuniform discharge and discharge channel split, occurs under low (<0.10%) or high (>0.35%) volume fractions of NH3, which are understood to be caused by an insufficiently strong Penning effect or a strong attachment reaction, respectively. The attachment reaction of NH3 can also lead to a weaker emission intensity for Ar/NH3 DBD, in particular regarding the emission of OH(A2Σ+). Ar/NH3 and He/N2 DBDs are also compared. In He/N2 DBD, the emission intensity of OH(A2Σ+) changes less with increasing N2 volume fraction, which may be attributed to the lack of attachment reaction. Compared with Ar/NH3 DBD, the single discharge channel in He/N2 DBD is narrower, but the discharge area is wider, which should be induced by the higher Townsend ionization coefficient nonlinearity of He/N2 and the absence of attachment reaction in He/N2, respectively. In the end, a one-dimensional fluid model of Ar/NH3 DBD is built to verify the explanation of experimental results.
