Abstract
Using continuous coating with Si-alkoxide as a binder, Cs2.5H0.5PW12O40 (Cs2.5) powder was prepared and immobilized onto a Pyrex glass plate. The Cs2.5 coating possessed an acid site on the film surface. Translucent TiO2–Cs2.5 hybrid films were prepared by laminating TiO2 films with holes on the Cs2.5 coating using phase-separation of alkoxide. Photocatalytic decomposition of 1,4-dioxane in water revealed that the holes serve as adsorption fields for ethylene glycol diformate, an intermediate with poor affinity to TiO2. The TiO2–Cs2.5 hybrid films produced by this process are candidates for purification of water containing several chemicals with a slow decomposition rate in photocatalysis.
