ABSTRACT

Discharge modes of surface dielectric barrier discharge are influenced by various factors, with its underlying mechanisms still unclear. This study explores the effects of power input and N2/O2 ratios on NOx yield and selectivity using Fourier Transform Infrared Spectroscopy and analyzes the spatiotemporal evolution of discharges under alternating current (AC) and pulsed power sources. Results show that NO2 selectivity is higher under pulsed power compared to AC, with a peak of 56.2% at 30% N2 content. Increased power enhances NO2 selectivity to 49.6% in the pulsed-driven system, while no significant change is observed with AC. The lower rotational temperature in pulsed power systems facilitates the O generation for further NO oxidation. These findings may provide new chemical insights into plasma-enabled nitrogen oxidation.
