PURPOSE: A titanium dioxide and a manufacturing method thereof are provided to reduce manufacturing cost of photocatalyst films by enabling large area manufacture, to enhance efficiency, and to reduce manufacturing cost of total system by not requiring a separate electrode and to miniaturize the device. CONSTITUTION: A titanium dioxide photocatalyst is manufactured by combining titan metallic films (30) equipped with a plurality of titanium dioxide nanotubes (30a) with a nano size diameter with metal mesh supporters (10). The metal mesh supporter is made of nickel. A manufacturing method of the titanium dioxide photocatalyst comprises the following steps: coating one side of the titan metallic film with metallic components; binding metal mesh as a supporter with an uncoated surface; forming titanium dioxide nanopores by oxide etching on the titan metallic film through anodizing; and forming titanium dioxide nanotubes on the titan metallic films by removing metallic components.
