PROBLEM TO BE SOLVED: To provide a metallic oxide having the shape of a nanotube or a nanowire and a large specific area and a method for producing the same, and also provide a titanium dioxide in an anatase phase which has a high photocatalytic capacity and a high specific area due to the shape of a nanotube, and a titanium dioxide or the like having a high dye-sensitized capacity and an electron transport capacity, and further, provide a highly active catalyst or a catalyst carrier, an electronic material, an optical material or the like, each having a nanotube or nanowire shape. SOLUTION: A metallic compound or its organic solvent solution and a surfactant are brought into contact with water, and subjected to mixing and solidifying, thus forming the metallic oxide having a nanotube or nanowire shape. |
