... According to a previous work [38], PVP is effectively depolymerized in the presence of H 2 O 2 . Numerous studies of the kinetics of hydrogen peroxide accumulation in plasma systems in contact with liquids have shown that the electrode material can be both a catalyst and an inhibitor of the decomposition reaction of hydrogen peroxide [39][40][41][42]. The results of measuring the concentration of hydrogen peroxide under conditions of a diaphragm discharge action in distilled water with Mo, Nb, and W electrodes are also presented in Table 1. ...

... Recently, nonthermal atmospheric-pressure plasma (NTAPP), which is an external energy source, has attracted attention as a method for generating reactive oxygen species (ROS) under mild conditions [1]. NTAPP can generate ROS in an energy saving and sustainable manner [2][3][4][5] because of its operation under ambient conditions, low input energy less than several hundred watts, and the utilization of gases with high abundance, such as air and argon, as the plasma source gas [1]. It has been reported that NTAPP-irradiated liquids (i.e., plasma-activated liquids) appear various functions due to ROS generated in the liquid phase [6]. ...

... In this case however, the light emission would not be directly related to the Faradaic charge transfer which governs the electrochemical behaviour of the system as pointed out in Section 4.1. One of possible (but not definitive) mechanisms underlying high-field electroluminescence also relies upon water decomposition and ionisation due to bombardment of the gas-electrolyte interface by energetic cations [80]: ...

... The dominant reaction pathway of lignin degradation is the cleavage of the C β -O covalent bond followed by the cleavage of the C β -C α bond. Titova et al. 150 investigated the chemical transformations of isoeugenol (2-methoxy-4-ppropenylphenol, a model lignin compound) under the combined action of an atmospheric pressure discharge initiated in the volume of an electrolyte and alkali treatment using UV spectrophotometric analysis. They found that plasma-solution activation was an initiator of the oxidative breakdown of the aromatic structure of the compound during alkali treatment. ...

... plasma zone initiating the formation of chemically active particles with excessive reactivity [6,7]. The formed active particles, namely, radicals and hydrogen peroxide, are capable of penetrating deep into a cell membrane thus activating the cell processes and affecting the initial stages of the plant development. ...

... Liu et al. [10] used a glow-like discharge plasma device to treat a sodium lactate solution, and the yield of hydrogen peroxide in activated sodium lactate is eight times higher than that of the PAW, reaching 325 μmol/L. Kuz'micheva et al. [11] found that the yield of H 2 O 2 increased from 5:2 � 10 −4 mol=L to 1:4 � 10 −3 mol=L when glow discharge plasma was used to treat 0.01 mol/L Na 2 SO 4 and 0.1 mol/L ethanol mixed solution compared with only 0.01 mol/L Na 2 SO 4 . In our previous study [12], a DC-driven air plasma device has been used to treat solution containing H+, NO − 2 and NO − 3 species and achieved a better decontamination effect than PAW. ...

... These reactive oxygen species (ROS) have strong oxidative activity, which can damage fungal membrane, resulting in spore inactivation (Sen Gupta, 2015). It has been reported that the increase of voltage and the decrease of electrode gap leads to the increase of electric field intensity between electrodes, the average energy of high-energy electrons becomes stronger, and more ROS is generated (Kuz'micheva, et al., 2007). Due to the presence of antioxidant substances such as polyphenols, flavonoids, carotenoids and vitamins in fruit juices, part of ROS produced by CGDE can be removed, resulting in reduced inactivation efficiency (Surowsky et al., 2015). ...

... Solution plasma processing (SPP) or plasma in the liquid phase is regarded as an advanced oxidation method because of its potential to generate highly active species, particularly hydroxyl radicals (Surov et al., 2018;Zakharov et al., 2007). In a study, Surov et al. (2018) reported a novel oxidation-hydrolysis method involving atmospheric pressure glow discharge SPP system for production of CNCs from MCC and filter paper (FP). ...
