CATALYTIC PROPERTIES OF SILICA PACKINGS UNDER OZONE SYNTHESIS CONDITIONS

The catalytic effect of dielectric packings inside the discharge gap o n the yield of ozone generation was studied under silent discharge con ditions. Porous silica of developed internal surface and quartz glass grains were used as the packings. In the presence of coarser grains of both materials, higher ozone concentrations and higher energy efficie ncy were observed than with the finer ones. Porous silica was found to be more effective than quartz glass. The higher activity of silica ar ises from the surface structure rather than from its porosity.
