Coaxial dielectric barrier discharge for plasma catalysis in N2 and H2 — •Roland Friedl1, David Rauner1, and Ursel Fantz1,2 — 1AG Experimentelle Plasmaphysik, Universität Augsburg, 86135 Augsburg — 2Max-Planck-Institut für Plasmaphysik, Boltzmannstr. 2, 85748 Garching
Dielectric barrier discharges (DBDs) are frequently utilized for plasma catalytic systems, due to their advantages regarding several crucial aspects: due to the repetitive filamented discharge, gas heating is avoided and distinctive non-equilibrium conditions are maintained at atmospheric pressure. In addition, if operated in a so-called packed-bed configuration, where the catalyst is coated on or embedded in the dielectric material, a large interaction area between the plasma and the active catalyst surface can be exploited.
In this contribution, a recently commissioned coaxial DBD setup is introduced, which is targeted towards the investigation of nitrogen and hydrogen discharges together with catalytic materials in a packed-bed configuration, e. g. in view of ammonia production. First investigations in view of an electrical and spectroscopical characterization are presented.
