Abstract: The present invention relates to a nitrogen doped porous TiO_2 nanostructure which has activity not only in the wavelength range of the ultraviolet rays, but also in the wavelength range of visible rays; and to a manufacturing method thereof. The nitrogen doped porous TiO_2 nanostructure of the present invention is characterized by having a plurality of pores of 200 nm or less. The manufacturing method for a nitrogen doped porous TiO_2 nanostructure of the present invention is characterized by comprising: (a) a step of mixing titanium alkoxide and an ammonia solution; (b) a step of filtering precipitates generated by performing mixing in the step (a); (c) a step of drying filtrates filtered in step (b); and (d) a step of heat-treating materials dried in the step (c).
