Abstract: A method for preparing impurity-doped titanium dioxide photocatalysts having superior photo activity at a visible light region and an ultraviolet light region in mass production. The titanium dioxide photocatalysts are prepared in mass production using low-price reusable materials at a room temperature when titanium dioxide is doped with carbon, sulfur, nitrogen, fluorine, and phosphorous. The method for preparing impurity-doped titanium dioxide representing superior photo activity in both of the ultraviolet light region and the visible light region in mass production includes: stirring titanium dioxide powder while mixing the titanium dioxide powder with a doping agent; performing ultrasonification with respect to a mixed solution; washing a reactant obtained through the ultrasonification by using a washing solution while performing pressure-reduction filtering with respect to the reactant; obtaining doped titanium dioxide particles by drying the reactant; and performing heat treatment with respect to the doped titanium dioxide particles at a nitrogen atmosphere.
