Abstract
Titania/smectite composites were synthesized by mixing of titania sol solution with smectite suspension. The obtained composites were characterized by XRD, XRF, TEM, XPS, and N2-BET. Photocatalytic property of the obtained samples was examined under UV radiation using various organic solutions or under various organic vapors. The obtained composite decomposed 1,4-dioxane in aqueous solution and the decomposition rate was as same as pure TiO2 powder under 400 nm UV.
