Abstract: PURPOSE: Substrate fixing titanium dioxide nano-wires, a method for manufacturing the same, and a water treating method using the same are provided to maximize the activity of a photo-catalyst by optimizing the crystal phase ratio of titanium dioxide. CONSTITUTION: A method for manufacturing a substrate fixing titanium dioxide nano-wires includes the following: Titanium dioxide nano-wires are fixed to a substrate. A mixed solution containing a titanium dioxide precursor and the substrate are prepared(S201). The mixed solution is electro-spun to the substrate in order to deposit the titanium dioxide nano-wires(S202). The titanium dioxide nano-wires are fixed on the substrate through a thermal compressing operation(S203). The anatase crystal phase and rutile crystal phase ratios of the titanium dioxide nano-wires are adjusted(S204).
