Extruded element non-thermal plasma reactors having a single dielectric barrier layer include a first barrier layer of a pair of opposing dielectric barrier layers forming an exhaust channel therebetween, the first barrier layer provided with a first polarity conductor on an interior surface thereof The second barrier layer of the pair of opposing barrier layers is provided with a second polarity conductor on the exhaust channel exterior surface, whereby the second barrier layer provides the single dielectric barrier layer. The second polarity conductor serves as a conductor on the channel interior surface of the adjacent exhaust channel in repetitive fashion until a reactor element of the desired size is achieved. The reactors are free of dedicated conductive passages, providing increased active exhaust channel volume compared to comparable double dielectric barrier elements. An electrode coating pattern having conductive coating extending fully to the side walls to connect with side bus connections eliminates the need for internal bus paths, thereby further improving volumetric efficiency. Single dielectric barrier planar and swept-shaped reactor elements have minimal or partially extending internal support ligaments providing enhanced conversion efficiency. In preferred embodiment, a swept-shaped reactor element, such as a concentric tube, is provided having an internal support ligament-free configuration. The ligament-free concentric tube embodiment provides increased conversion efficiency and thin wall capability over comparable single tube reactors.
