Abstract
An object of the present invention is to provide an ozone adsorbent which has high ozone-adsorbing power even in a moisture-containing system and exhibits a high degree of ozone retention (and a low degree of ozone decomposition), as well as a molded product made by molding this ozone adsorbent into a form adapted to practical use, and a method of making the same. The present invention provides an ozone adsorbent comprising one or more members selected from the group consisting of high-silica pentasilzeolite having a SiO,/Al,O,ratio of not less than 70, dealuminized faujasite having a SiO,/Al,O,ratio of not less than 20, and mesoporous silicate having a SiO,/Al,O,ratio of not less than 20, as well as an ozone-adsorbing molded product and a method of making the same.
