摘要： A titanium dioxide complex capable of distinguishing molecules is obtained by modifying the surface of a fine titanium dioxide particle with a hydrophilic polymer in such a manner that titanium dioxide is bonded via an ester bond to a carboxyl group of the hydrophilic polymer and immobilizing a molecule having an ability to specifically bind to a target molecule to the carboxyl residue of the hydrophilic polymer. Due to the molecule distinguishability, this titanium dioxide complex can bind specifically to an endocrine disrupting chemical, a pathogenic factor, a cancer cell, etc. and decompose the same by a photocatalytic function.

摘要： Surface-modified titanium dioxide fine particles which have a surface chemically modified with a hydrophilic polymer, wherein a carboxyl group of the hydrophilic polymer and titanium dioxide are bound through an ester bonding; and a method for producing the surface-modified titanium dioxide fine particles, which comprises mixing a dispersion comprising titanium dioxide fine particles having a particle size of 2 to 200 nm and a solution of a water-soluble polymer, heating the resultant mixture to a temperature of 80 to 220°C, to thereby bind both the components through an ester bonding, and removing an unbound water-soluble polymer, to purify the resultant particles. The surface -modified titanium dioxide fine particles exhibit excellent dispersibility and stability in an aqueous solvent over a wide pH region including a neutral range.

摘要： Disclosed is a sanitary ware including a photocatalyst layer that has a high level of water resistance and abrasion resistance while maintaining a good photocatalytic activity. The sanitary ware includes a glaze layer and a photocatalyst layer provided on the glaze layer. The photocatalyst layer is an oxide film that is a co-fired product of a precursor of titanium oxide and a precursor of zirconium oxide and contains 65 to 90% by mass of titanium oxide and 10 to 35% by mass of zirconium oxide.
