<p>A titanium oxide-based photocatalyst composed mainly of a photocatalyst base material and a silicon compound, the base material comprising zirconium titanate with an atomic percentage ratio of zirconium to titanium of 0.001 to 0.5. This photocatalyst can form, on the surface of a substrate of a metallic material, an inorganic material, an organic material or the like, a photocatalyst layer having good adhesion to the substrate and good film properties, such as good processability and strength. The photocatalyst can be prepared by coating the surface of a substrate with a composition comprising a base material for a photocatalyst, a silicon compound, and a solvent and baking the coating. A material carrying the photocatalyst thereon enables a harmful material in the atmosphere or in water, or a material deposited on the material to be decomposed, rendered harmless or removed under light irradiation.</p> |
