Abstract

New data are reported on the catalytic activity of silica in the ozone formation under silent discharge conditions. For the first time, the stable catalytic effect was observed not only during the ozone production from oxygen but also-from air. A hypothetical scheme of the catalytic ozone synthesis in the presence of granular dielectrics is discussed. Using a simplified model of the discharge gap, a hypothesis has been proposed on the essential role of surface discharges (on the dielectric grains) in the catalytic process.
