| Outline of Final Research Achievements |
Plasma on the surface of catalyst was consisted of primary and secondary streamers. The different activities of Ag and Pt in plasma-catalysis were found to be correlated with the properties of streamer propagation. The propagation velocity of primary streamers was found to be dependent on the applied voltage and the type of catalyst. For the Ag/TiO2 catalyst-packed-bed reactor with a mesh-to-mesh configuration, the primary streamer reached about 660 km/s. Through successive steps, the partial discharge served as a staging point for primary streamers, and promoted their propagation toward the next catalyst bead. In contrast to primary streamers, secondary streamer velocities were almost completely independent of the applied voltage. These finding may provide some useful insight in understanding fundamental working mechanism of plasma-catalysis.
