The Effect of Inert Gases on Ozone Generation Using Dielectric Barrier Discharge in Dry Air

Abstract

This experiment studies the effect of inert gases He, Ar, Kr and Xe on ozone generation within a dielectric barrier discharge reactor fed by dry air. The results show that increasing inert gas content leads to a lower applied voltage, discharge power and reduced field. Although the addition of inert gas would lead to a lower reduced field, however, the electron energy distribution function still shifts to the right. The electron density increases slightly at first and then decreases steadily with increasing Xe content, but it decreases monotonically with increasing content of He, Ar and Kr. With regard to dry air/Kr and air/Xe mixtures, ozone concentration and ozone yield show a slight initial increase, followed by a steady decrease for and , which are favorable for ozone production through the Penning dissociation of O₂ due to their lower excitation energy.
