“…We observed asymmetric PIE waveforms together with asymmetric waveforms of the capacitor voltage u C . Similar asymmetric SDBD behaviour has already been reported [13][14][15][16]. However, the spectrometric confirmation of this asymmetry through the variation of the ratio of O I /O 2 ?…”

The measurements of electro-optical discharge characteristics and concentration of produced ozone were performed to evaluate the efficiency of ozone production in an AC surface dielectric barrier discharge (SDBD) in pure oxygen at atmospheric pressure. The discharge was driven in an amplitude-modulated regime with a driving AC frequency of 1 kHz, variable discharge duty cycle of 0.01-0.8 and oxygen flow rate of 2.5-10 slm. We observed asymmetric SDBD behaviour as evidenced by the variation in the ratio of the O I /O 2 ? emission intensities registered during the positive/negative half-periods and complemented by the transferred charge measurements through the Lissajous figures. We also found a strong dependence of O 3 concentration on the discharge duty cycle. The highest calculated ozone production yield reached 170 g/kWh with a corresponding energy cost of about 10 eV/molecule when combining the lowest inspected duty cycle with the lowest AC high voltage amplitude.

“…4. The microdischarges occur in every half period of applied voltage for the alternating voltage of 2.7 kV with 2 kHz (Massines et al, 1988;Abdel-Salam et al, 2003;Korzec et al, 2003). Thus, the occurrence of these microdischarges confirmed the typical performance of the SMAC used in this study.…”

“…DBD can be configured in two basic arrangements, that is, the volume discharge arrangement and surface discharge arrangement, as well as many combinations of the two (Gibalov & Pietsch, 2000;Korzec et al, 2003). In the present study we used the surface discharge arrangement.…”

“…The other discharges, which are intentionally generated on the dielectric surface (Haacke et al 2002;Korzec et al 2003;Masuda et al 1988;Nomoto and Kanazawa 1995), are of great importance. Some arrangements of the discharge space are unconventional, due to which the process higher yields are obtained (Jung and Moon 2008;Takaki et al 2009).…”

Results of studies on ozone synthesis under discharges proceeding in a metal mesh-ceramic dielectric system have been presented. The experiments were carried out in the reactor with unique reaction space geometry, in which the reacting gas flew with consequently increasing linear velocity. The high voltage electrode was made of a metal mesh, which caused intensification of the gas mixing in the reaction space. Using a simple reactor with one-side cooling of the reaction space, high ozone maximum concentrations (100 g/Nm 3 ) and energy efficiencies were obtained at 25 • C.
