Electrical and Reaction Performances of Packed-bed Plasma Reactors Moderated with Ferroelectric or Dielectric Materials

The operational behavior of packed bed plasma reactors depends on the dimension, shape and chemical properties of the pellets used as moderators, but little information exists about the influence of their specific dielectric properties. Herein, we comparatively study the electrical behavior of a pac...
