Disclosed is a vanadium/titania-based catalyst including natural manganese ore for removing nitrogen oxides and dioxin in a wide operating temperature range and a method of using the same. Specifically, this invention pertains to a vanadium/titania (V/TiO)-based catalyst, including natural manganese ore, and a method for removing nitrogen oxides and dioxin over a wide operating temperature range, in which the WTiOcatalyst for selective catalytic reduction of nitrogen oxides and removal of dioxin contained in flue gas includes 5-30 wt % of natural manganese ore.

Disclosed are a method for preparing a catalyst, which has excellent nitrogen oxide-removal performance and resistance over a wide temperature range, and the use of the catalyst. According to the disclosed method, the oxidation number and surface defects of the catalyst are changed by applying artificial high energy through mechanical ball milling during the preparation process of the catalyst, instead of applying the addition of a precious metal, the deformation of a support and the use of a co-catalyst in order to increase NOx removal activity, such that activation energy for inducing redox reactions can be decreased.
