“…[25] Whereas a direct (although not lineal) frequency dependence is well-known and addressed in electromagnetism books, [32] voltage dependence, which comes from the ferroelectric hysteresis loop (polarization vs. electric field representation), is currently under research. [33,34] It is noteworthy that similar dependences on frequency and voltage should also affect the evolution of reaction efficiencies in a large variety of plasma-catalysis processes [4,9,10,[35][36][37][38] where, unfortunately, the lack of systematic comparative studies has precluded obtaining clear evidence about the effect of the dielectric constant of moderator materials on reactor performance.…”

The operational behavior of packed‐bed plasma reactors depends on the dimension, shape, and chemical properties of the pellets used as moderators, but little information exists about the influence of their specific dielectric properties. Herein, we comparatively study the electrical behavior of a packed‐bed reactor filled with pellets of either dielectric (Al2O3 and glass) or ferroelectric (BaTiO3 and lead zirconate titanate) materials. We found that plasma current was higher for ferroelectrics and presented a nonlineal dependence on voltage. Moreover, for BaTiO3, we found a drastic decrease at around its relatively low Curie temperature. Differences in electrical behavior have a direct effect on the reactor performance, as illustrated for the ammonia synthesis, demonstrating the importance of moderator material dielectric properties and their dependence on temperature.

“…In the former, the catalyst is directly located into the NTP reactor, which can be filled with the catalyst either totally (as in a packed-bed or monolithic reactor) [148][149][150][151] or partially (as in the hybrid reactor) [152][153][154]. In the last decade, different reviews have been published regarding the combined use of NTP and catalysts in the abatement of the several VOCs categories; all the reviews have considered all the main features, including reactor configuration, catalysts typology, catalyst placement, discharge power, number of electrodes [9,[142][143][144][155][156][157][158][159][160]. The analysis of these reviews evidenced the enormous interest of the scientific community towards the issue of the VOCs abatement by means of the catalytic NTP-assisted oxidation processes, especially by using packed bed or DBD reactors.…”

Plasma science has attracted the interest of researchers in various disciplines since the 1990s. This continuously evolving field has spawned investigations into several applications, including industrial sterilization, pollution control, polymer science, food safety and biomedicine. nonthermal plasma (NTP) can promote the occurrence of chemical reactions in a lower operating temperature range, condition in which, in a conventional process, a catalyst is generally not active. The aim, when using NTP, is to selectively transfer electrical energy to the electrons, generating free radicals through collisions and promoting the desired chemical changes without spending energy in heating the system. Therefore, NTP can be used in various fields, such as NOx removal from exhaust gases, soot removal from diesel engine exhaust, volatile organic compound (VOC) decomposition, industrial applications, such as ammonia production or methanation reaction (Sabatier reaction). The combination of NTP technology with catalysts is a promising option to improve selectivity and efficiency in some chemical processes. In this review, recent advances in selected nonthermal plasma assisted solid–gas processes are introduced, and the attention was mainly focused on the use of the dielectric barrier discharge (DBD) reactors.

“…Therefore, the gas‐phase parameters of VOCs, such as the kind of gas, initial concentration, and flow rate, usually affect the degradation effect. [ 101 ] Different kinds of VOCs have different degradation efficiencies because of the structure and chemical bond energy as well as the degradation pathway of VOCs. Karatum and Deshusses [ 45 ] carried out degradation experiments on different VOCs under the same experimental conditions.…”

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.
