    Abstract: Provided are a method for conveniently preparing a quantity of titanium dioxide nanorod, a nanorod prepared by the method which has a uniform and large surface area and can be used for dye sensitized solar cell, sensor, photocatalyst, and so on. The method comprises the steps of (i) preparing a mixture solution comprising a precursor of titanium dioxide, a polymer compatible with the precursor, and a solvent, (ii) spinning the mixture solution, so as to form a titanium dioxide-polymer composite fiber containing fine fiber therein by phase separation of the precursor of titanium dioxide and the polymer, (iii) heat-pressing the composite fiber, (iv) removing the polymer from the composite fiber to obtain a titanium dioxide nanorod. The dye sensitized solar cell, sensor, and photocatalyst are manufactured by a metal plate having an aggregate of the titanium dioxide nanorod, a transparent and conductive glass substrate or plastic substrate coated with ITO(indium-doped tin oxide) or FTO(fluorine-doped tin oxide).
