Volatile organic compounds (VOCs) emissions are a factor in a number of environmental issues. To reduce the associated negative consequences, it is crucial to develop efficient VOCs removal systems. Non‐thermal plasma (NTP) co‐catalytic technology has become a popular research topic in this field as a result of its ability to reduce the activation energy of the reaction while simultaneously improving product selectivity. Despite the huge number of studies synthesising the use of metals and their oxide catalysts in the degradation of VOCs, metal‐organic frameworks (MOFs) and MOF derivatives are the subject of comparatively few studies in this area. This paper reviews the basic principles and technological progress of NTP co‐catalytic VOCs degradation, with a focus on the use of MOFs and their derivatives in plasma VOCs degradation, as well as the use of other non‐metallic carbon materials in plasma VOCs degradation. It highlights the potential future development direction of NTP catalytic synergistic treatment of VOCs by focusing on the optimization of catalytic synergism on the treatment impact. In the end, the challenges faced, the prospects, and our personal perspective on future research directions are also estimated and elucidated.

“… 13 However, the preparation and modification of catalysts for plasma reactions should not completely follow the same principle as those for thermal reactions since a catalyst might behave differently in plasma and thermal reactions. 14 For instance, our previous study demonstrated that the K- and Ce-promoted Ni/Al 2 O 3 catalysts enhanced the conversion of CO 2 compared to Ni/Al 2 O 3 , while the use of Mg-promoted catalysts had a negative impact on CO 2 conversion in plasma-catalytic biogas reforming. However, K-, Mg-, and Ce-promoted catalysts showed antipodal activities in thermal-catalytic biogas reforming, where only the Mg-promoted Ni catalyst promoted CO 2 conversion.…”

The removal of tar and CO2 in syngas from biomass gasification is crucial for the upgrading and utilization of syngas. CO2 reforming of tar (CRT) is a potential solution which simultaneously converts the undesirable tar and CO2 to syngas. In this study, a hybrid dielectric barrier discharge (DBD) plasma-catalytic system was developed for the CO2 reforming of toluene, a model tar compound, at a low temperature (∼200 °C) and ambient pressure. Periclase-phase (Mg, Al)O x nanosheet-supported NiFe alloy catalysts with various Ni/Fe ratios were synthesized from ultrathin Ni–Fe–Mg–Al hydrotalcite precursors and employed in the plasma-catalytic CRT reaction. The result demonstrated that the plasma-catalytic system is promising in promoting the low-temperature CRT reaction by generating synergy between DBD plasma and the catalyst. Among the various catalysts, Ni4Fe1-R exhibited superior activity and stability because of its highest specific surface area, which not only provided sufficient active sites for the adsorption of reactants and intermediates but also enhanced the electric field in the plasma. Furthermore, the stronger lattice distortion of Ni4Fe1-R provided more isolated O2– for CO2 adsorption, and having the most intensive interaction between Ni and Fe in Ni4Fe1-R restrained the catalyst deactivation induced by the segregation of Fe from the alloy to form FeO x . Finally, in situ Fourier transform infrared spectroscopy combined with comprehensive catalyst characterization was used to elucidate the reaction mechanism of the plasma-catalytic CRT reaction and gain new insights into the plasma-catalyst interfacial effect.

“…Atmospheric plasmas are generated by various sources such as glow discharges, and dielectric barrier discharges [1, 2], and comprise of excited and charged species such as electrons, ions, and radicals. Since its introduction in the mid‐1990s, atmospheric plasmas have been widely used in biology, medicine, nanomaterial synthesis, and water and air treatment because of its abilities to achieve high electron densities, produce reactive oxygen species and reactive nitrogen species, and emit UV radiation [3–6]. These abilities are a result of inherent non‐equilibrium in typical atmospheric plasmas where electrons exhibit temperatures of ≥10 4 K, while other ionic and neutral species present in the discharge are present at slightly above room temperature (~300 K) [7].…”

The low temperature atmospheric plasma are kinds of advanced oxidation processes (AOPs) reactors and have potential applications on gas cleaning and water treatment; however, the underlying reaction mechanisms of organic compounds degradation are not well understood. In this study, the gas phase multistep OH‐initiated dehydrogenations of p‐, m‐, and o‐phenylenediamine with C2h, C2, and C2 point groups were investigated using density functional theory. Intrinsic reaction calculations were performed for transition states at the M062X/Def2TZVPP level of theory. The distinct directed graphs of the predominant pathways are presented to elucidate the dehydrogenation processes of three isomers of phenylenediamines. The information reported in this paper reveals the AOPs of phenylenediamines.
