Document Type and Number:

WIPO Patent Application WO/2000/046154

Kind Code:

A1

Abstract:

A novel process for producing anatase titania or a composite oxide containing anatase titania which is useful as a photocatalyst, bactericidal material, or antibacterial material and can be produced in various shapes at a temperature as low as 100 °C or below, characterized by forming a gel comprising a metal oxide from a solution of a hydrolyzable titanium compound and then reacting the gel with water at 100 °C or lower to produce the target titania or composite oxide.
