This paper was to synthesize a photocatalytic TiO₂/ZnTiO₃ coating on glazed ceramic tiles by the sol-gel method and subsequent thermal treatment. The structural and morphological properties were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The result reveals that the photocatalytic coating is composed of anatase TiO₂ and hexagonal ZnTiO₃. The average particle size of the anatase TiO₂/ZnTiO₃ is about 50 nm. In addition, the photocatalytic performance was carried out by the decomposition of methylene blue solution under UV light irradiation. The anatase TiO₂/ZnTiO₃ coating exhibits higher photocatalytic activity than that of pure anatase TiO₂ coating and rutile TiO₂/ZnTiO₃ coating.
