Abstract: In this article, the effect of zeolite chemical surface properties on gaseous ozone removal was investigated. Zeolite samples with different surface chemical composition were prepared from a Chilean natural zeolite. Such treatments included acid de-alumination, and thermal treatment at 400 °C and 550 °C prior to contact with ozone. Chemical modification of natural zeolite showed that the generation of new Lewis acid sites on zeolite surface increases ozone removal. It is concluded that Lewis acid sites present on zeolite surface play a key role enhancing the gaseous ozone elimination. [ABSTRACT FROM AUTHOR]
