Plasma-based NOx synthesis has attracted considerable attention as an alternative nitrogen fixation technology. In this study, high-concentration NOx was generated from air using an atmospheric-pressure rotating gliding arc plasma reactor. Dry air was employed as the feed gas, and the effects of discharge conditions on NOx production were investigated. The concentrations of NO and NO2were quantified using FTIR spectroscopy. The results demonstrate the potential of RGA plasma for energy-efficient NOx synthesis, which is expected to promote subsequent N2O5 production and improve the overall efficiency of plasma-assisted nitrogen fixation.
