“…The detoxification of air pollution caused by volatile organic compounds (VOCs, such as TCE, TCA, toluene, and xylene), acid and greenhouse gases (such as SO x , NO x , HCl, CO x , N x O y , and PFCs), or ozone depletion substances (Freon or Halon) may be assisted by plasma . Generally, a number of pollutants are present in waste air, and plasma decomposes different hazardous air pollutants at the same time . Plasma removes toxic particles in shipping diesel engine exhaust gases, including NO x .…”

Cold physical plasmas ignited a technological spark in industry, biotechnology, and medicine. Especially the field of hygiene benefited of the plasma's exceptional activity against pathogenic microorganisms. Together with plasma-based surface functionalization, these qualities are highly relevant in a variety of processes in health care, such as the decontamination or sterilization of medical devices, food, packaging materials, waste water, or indoor air. In medicine, plasma has proven to show promising antiseptic results on skin and mucosal membranes in infection-related diseases in dermatology and dentistry. This comprehensive review will discuss the current applications of cold plasma in the fields of hygiene, and will provide a promising outlook on many applications yet to come.

The paper presents investigations of self-pulsing discharges in atmospheric pressure air preheated to 300-1000 K. Despite using a direct-current power supply, two self-pulsing discharge regimes, a repetitive transient spark (TS) and a repetitive streamer (RS) were generated. The pulse repetition frequency, on the order of a few kHz, can be controlled by adjusting the generator voltage. The TS is a discharge initiated by a streamer, followed by a short (tens of ns) spark current pulse (∼ 1 A), associated with the total discharging of the internal capacity of the electric circuit. The TS is suitable for the study of 'memory' effects (pre-heating, preionization) on the mechanisms of streamer-to-spark transition and electrical breakdown in atmospheric pressure air. The TS regime was stable below ∼600 K. Above ∼600 K, a stable repetitive streamer (RS) regime was observed. In this regime, the breakdown and spark did not occur. After the initial streamer, the internal capacity of the electrical circuit discharged partially. With further pre-heating of the gas, the stable TS appeared again at ∼1000 K.

“…Liu et al [150] reported that the neural network model can accurately simulate and predict the influence of gas flow rate, frequency, and power on the non-oxidative conversion of methane in a DBD reactor. Derakhshesh et al [151] established a model for predicting the effluent concentration in a pulsed corona reactor based on the mass balance in terms of linear velocity, axial dispersion, and decomposition rate of pollutant, and the result showed that data gained from the model fitted well with the experimental data. Costa et al [152] proposed a kinetic degradation model taking into account the humidity and electron impact generated by plasma on water molecules which described successfully the butyraldehyde removal efficiency, mineralization, and ozone production in a surface plasma reactor.…”

The combination of non-thermal plasma (NTP) and catalyst characterized by high energy efficiency, enhanced volatile organic compounds (VOCs) removal efficiency, high product selectivity, and low production of unwanted and/or toxic by-products possesses a great promise for the abatement of VOCs. This work reviews the state of knowledge regarding Mn-based catalysts for VOCs abatement in the post-plasma-catalytic (PPC) system. First, the development and the performance of different Mn-based catalysts such as pure manganese oxide, mixed manganese oxide-based catalysts, and supported Mn-based catalysts in terms of VOCs abatement and O 3 decomposition are summarized. Then, the mechanism of the VOCs decomposition in the NTP and PPC system is discussed. Finally, the modeling and simulation of VOCs abatement in the NTP and PPC system are overviewed. This review aims at providing a reference guide for the development and optimization of VOCs abatement in the PPC system using Mn-based catalysts.
