【 摘 要 】

References(25)Cited-By(1)An experimental and theoretical study on nitric oxide (NO) was carried out in a dielectric barrier discharge (DBD) reactor with various electrode configurations. Two different configurations, a dentate electrode and columnar electrode, were employed as a ground electrode. The electric field near the inner electrode was stronger with the dentate electrode, enhancing the disassociation and excitation rate of N2. When the energy density was 375 J/L, the NO removal in the dentate electrode reactor was 2.6 times higher than that in the columnar electrode reactor. The maximum energy efficiency for NO removal was 6.9×10−6 g/J in the dentate electrode reactor, as the NO removal efficiency was 31%, which was higher than 6.1×10−6 g/J for the columnar electrode reactor. The equivalent capacitance and field distribution also changed under various electrode configurations, and the discharge power was higher in the dentate electrode reactor under the same applied voltage.
