Study on the Physical and Chemical Characteristics of DBD: The Effect of N 2 /O 2 Mixture Ratio on the Product Regulation

摘要: The chemical product behaviors of dielectric barrier discharge (DBD) in N2/O2 gas mixtures are investigated. Besides ozone mode and nitrogen oxides mode, a transitional which O3 NO2 coexist is observed. Under higher oxygen content condition, applied voltage lower flow rate contribute to the appearance mode. To further investigate physical characteristics DBD under different contents, energy per area introduced. It presents positive relationship with negative rate. And than that but As rises, critical transition increases. Through analysis products, it found beneficial generation O3. NO concentration positively correlated voltage. optimum for obtaining maximum increases rise With respect N2O, they easier be obtained at condition. case rate, its generation. Besides, N2O5 tends 50%
