Abstract

Ozone production in a planar dielectric barrier discharge (DBD) in atmospheric oxygen in different discharge modes was investigated. Results show that the gas temperature in discharge channel depends strongly on discharge mode, with a value of 300–310 K in glow regime and 440–465 K in streamer regime. Ozone production yield in glow DBD is much higher than that in streamer one, with the best yield of 342.6 and 162.6 g/kWh, respectively. Gas temperature in discharge channel relates to the effective discharge area of DBD, which is a small fraction of the whole electrode surface in streamer DBD compared with nearly the whole surface in glow DBD. The gas temperature in the channel plays a decisive role in the conversion of oxygen atoms to ozone as well as the ozone equilibrium concentration. Excellent performance of glow DBD demonstrates the high energy efficiency and reliability for practical application of planar DBD-based ozone generator.

不同模式平面 DBD 中臭氧生成量的比较

研究了平面介质阻挡放电（DBD）在大气氧气中以不同放电模式产生臭氧的情况。结果表明，放电通道中的气体温度与放电模式密切相关，辉光放电模式下的气体温度为 300-310 K，流光放电模式下的气体温度为 440-465 K。辉光 DBD 的臭氧产量远高于流式 DBD，最佳产量分别为 342.6 克/千瓦时和 162.6 克/千瓦时。放电通道中的气体温度与 DBD 的有效放电面积有关，在流式 DBD 中，有效放电面积只占整个电极表面的一小部分，而在辉光 DBD 中，有效放电面积几乎占整个电极表面。放电通道中的气体温度对氧原子向臭氧的转化以及臭氧的平衡浓度起着决定性作用。辉光 DBD 的优异性能证明了基于平面 DBD 的臭氧发生器的高能效和实际应用的可靠性。

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
