Ozone removal in corona discharge devices

摘要

Ozone-containing gas from a corona discharge device (7) e.g. in electrostatographic copying equipment passes through an ozone removal means (6) consisting of an ozone catalyst- or ozone adsorbent- impregnated porous body consisting of porous ceramic, reticulated vitreous carbon or foamed metal. In a preferred mode, ozone gas passes through a porous reticulated vitreous carbon having a co-precipitate of manganese oxide and cupric oxide impregnated therein.
