Abstract
The present invention provides a doped titanium oxide having visible light-responsiveness whose structure is specified, and a simple production method thereof. By burning with heat a layered structure composite laminated alternately with polymer and the titania, which is obtained using basic polymer having amino group(s) and water-soluble titanium compound, carbon atoms and nitrogen atoms in the polymer are, doped to the crystalline surface of titanium oxide. As making the polymer complex with metal ions beforehand, the metal ions can be also doped to the titanium oxide.
