Outline of Final Research Achievements

In order to clarify the mechanism of ozone zero phenomenon and to improve the ozone generation efficiency of air-fed ozone generation, the generation process of ozone and nitrogen oxide in a dielectric barrier discharge (DBD) ozonizer is investigated by observing the transmittance of the laser beam propagating through the DBD plasma. Discharge poisoning (DP) regime, in which no ozone is obtained from the air-fed ozonizer, is observed when the ozonizer is operated under a high energy density condition. Generation processes of ozone and nitrogen oxide in the air-fed ozonizer with and without the DP regime are discussed by the results of the exhaust-gas analysis by the Fourier transform infrared (FT-IR) spectrophotometer and the laser absorption experiment in the DBD plasma.
