Oxidation process of xylene in air using Ag/TiO$$_{2}$$ under electron beam irradiation

Hakoda, Teruyuki; Matsumoto, Kanae; Mizuno, Akira*; Narita, Tadashi*; Kojima, Takuji; Hirota, Koichi

Oxidation of xylene and its irradiation-induced organic byproducts in air using Ag-loaded TiO$$_{2}$$ (Ag/TiO$$_{2}$$) beds was studied under electron beam (EB) irradiation. The Ag/TiO$$_{2}$$ beds were placed in an irradiation or a non-irradiation space in order to identify the oxidation of xylene/its byproducts by EB irradiation, by catalytic process, and by a combination of the two. Placement of the Ag/TiO$$_{2}$$ bed to the irradiation space resulted in the suppression of xylene decomposition. On the other hand, production of CO$$_{2}$$ was observed in the gas phase of the irradiation space and on the surface of the Ag/TiO$$_{2}$$ pellets placed both in the irradiation and non-irradiation spaces. The concentration of CO$$_{2}$$ became higher when the layer was placed in the non-irradiation space. The production of CO$$_{2}$$ was enhanced by loading of Ag to the TiO$$_{2}$$ pellet surface. The highest concentration of CO$$_{2}$$ was obtained for Ag/TiO$$_{2}$$ with Ag contents greater than 5wt%.
