Abstract
Titanium dioxide (TiO2) photcatalytic thin films were prepared by sol-gel method. These films were characterized by the presence of the crystal by the measurement of X-ray diffraction and the surface observation with a the optical microscope. This research aims at preparation of TiO2 thin film of the Anatase type crystal known to have an especially strong effect of the photocatalyst.
Moreover, to confirm the effect of the photocatalyst, the resolution of methylene blue solution was experimented. It was refined that the condition of making the crystal of the Anatase type from this experiment. And, the effect of the photocatalyst was confirmed.
