“…Nonthermal plasma technologies, which are mainly applied for ozone synthesis as firstly developed, have been under extensive investigation for the removal of a variety of pollutants, including NO x , SO x , VOCs, and dioxin from gas streams [13,14]. Dielectric barrier discharge (DBD), the mainstream nonthermal plasma used for ozone generation, can be divided into four types based on the reactor geometry: typical DBD, surface discharge, coplanar discharge, and packed-bed discharge.…”
