Abstract: PURPOSE: A polycrystalline titanium dioxide-based nano-rod and a method for manufacturing the same are provided to simply ensure high efficient photocatalytic activity based on amorphous or low crystalline titanium dioxide photocatalytic particles through an electro-spinning process. CONSTITUTION: A method for manufacturing polycrystalline titanium dioxide-based nano-rod includes the following: Titanium dioxide nano-particles are mixed with a polymer solution. The mixed solution is undergone through an electro-spinning process. A resultant is sintered under the oxygen atmosphere about 450 degrees Celsius. The titanium dioxide nano-particles include amorphous, anatase, rutile, and at least one titanium dioxide selected from the same.
