PURPOSE: A TiO2 optical catalyst and a manufacturing method thereof are provided to easily give a visible light response property to TiO2 powder having an ultraviolet ray response property in an economic method without a transition metal or the doping of fluorine. CONSTITUTION: The manufacturing method of a TiO2 optical catalyst gives a visible light response property to TiO2 powder by applying a mechanical energy to TiO2 powder under water and reforming the surface of the TiO2 powder. The mechanical energy application is performed in one or more method selected among ball milling, tube milling, conical milling], rod milling, planetary milling, bead milling, jet milling, attrition milling, colloid milling, and wheeler milling. The TiO2 powder has one or more of anatase phase and rutile phase. The TiO2 optical catalyst has a visible light response property by reforming the surface of TiO2 powder in a form which OH and H2O are attached to. |
