Summary: This study investigates the catalytic routes for upgrading CO2 through the Sabatier reaction using non-thermal plasma. The impacts of reactor geometry, plasma conditions, and catalyst promoters on plasma discharge and CO2 conversion are studied. The results show that the catalysts perform better in plasma discharge at lower temperatures than in thermal conversion at 400°C.

Summary: Plasma-assisted conversion of ethane can produce value-added chemical building blocks. The selectivity of ethylene production is primarily determined by ethane conversion, and is not affected by the dielectric properties of the packed bed material, packing material size, supplied power, and ethane concentration. Particle size mainly affects conversion due to pressure alterations. Pd/SiO2 catalyst can change the selectivity by favoring saturated species.

Summary: Plasma-based CO2 capture and splitting have been successfully achieved in this study, which can be instantly initiated after the ignition of plasma and stopped when the plasma is turned off. A certain amount of CO was produced during the plasma treatment, with an average conversion rate of 41.14% of CO2. The potential application of this technology in syngas production and CO2 emission reduction from power plants has been discussed based on its technological advantages.

Summary: This study evaluated the thermal energy release and efficiency of a Radio-Frequency BDI through pressure-based calorimetry in a controlled environment. The experiment showed that the discharge duration and intensity played a significant role in the thermal energy release. The results indicated similar trends in absorbed and released energy between nitrogen and air, with up to 50% differences found in the latter, which exhibited a linear trend in contrast to the quadratic one in the LTP corona streamer-type igniter.

Summary: The combination of dielectric barrier discharge (DBD) of non-thermal plasmas with a self-made photocatalyst effectively removed isopropanol (IPA). By varying synthesis conditions for the photocatalyst and observing factors such as initial IPA concentration, oxygen content, and catalyst dosage, optimal reaction efficiency was achieved.

Summary: Steam methane reforming was conducted in a dielectric barrier plasma reactor, and a systematic study was carried out to investigate the effects of input power, flow rate, and water on the conversion, yield, and selectivity of the reaction using specially designed catalysts. The production rate and selectivity of H2, CO, and C2 hydrocarbons were monitored. CeO2 was used as the packing material mixed with oxides of manganese or copper. The optimum Cu/CeO2 catalyst exhibited a production rate of 248.7 mmolg-1h-1 for H2 and 11.25 mmolg-1h-1 for CO at a specific energy input of 19.8 JL-1. DFT calculations showed a significant change in the electronic structure of CeO2 after the inclusion of oxides of manganese and copper, enhancing the interaction with methane. Based on these findings, a plausible mechanism was elucidated for the design of catalysts for other applications in a non-thermal plasma atmosphere.

Summary: This study experimentally investigates the effects of various electrical parameters on the discharge and thermal characteristics of DBD plasma reactors. The results show that the discharge power and thermal efficiency increase with increasing peak-to-peak voltage, while they vary with frequency and airflow velocity. Additionally, they increase with increasing input airflow temperature.

Summary: This study explores the impact of electric field distribution on the uniformity of dielectric barrier discharge (DBD) in air at atmospheric pressure. It demonstrates that uneven electric field distributions can control the development of electron avalanches and result in enhanced Townsend discharge, which is beneficial for industrial applications. The findings provide insights into the relationship between electron avalanche transition and the formation of a uniform DBD, offering valuable references for future DBD development and applications.

Summary: The aim of this study was to optimize the performance of Non-Thermal Plasma (NTP) technology combined with a structured catalyst for the degradation of organic and recalcitrant pollutants in aqueous solution. The results showed that the catalyst formulation and oxygen flow rate had an impact on the degradation efficiency, and the catalyst exhibited reusability properties. Ozone and plasma-generated UV radiation were found to be the key reactive species, and the semiconductor properties of the catalyst may also contribute to the degradation mechanism. The study highlights the importance of this technology in the treatment of water pollutants.

Summary: This study investigated the effect of Cold Atmospheric Plasma (CAP) on the quality parameters of hairtail during cold storage. The results showed that CAP treatment significantly reduced the total bacteria count and total volatile basic nitrogen content, as well as slowed down the change in color. CAP-treated hairtail also had a longer shelf-life and better sensory attributes compared to untreated samples.

Summary: In this study, a parametrical investigation of hydroxyl radical (OH) production in nanosecond dielectric barrier discharge (DBD) in He/air mixture was carried out using laser-induced fluorescence method. The differences between uniform and non-uniform modes of discharges, as well as the disparity in OH and H2O2 production, were the main focuses. The results indicate that the amount of OH generated in the gas phase and the delivery rate of downstream H2O2 to liquid depend on the mode of discharge operation, with the non-uniform DBD showing 30% and 3 times higher levels, respectively, compared to the diffuse discharge.
