Abstract
Provided is a denitration catalyst with an improved wear resistance capable of stably reducing and removing nitrogen oxides in flue gases for a long period of time and a production method therefor. A denitration catalyst obtained by having a honey comb molded body that contains at least titanium oxide and vanadium pentoxide support magnesium surface, and wherein the peak intensity ratio of the first peak of the magnesium sulfate to the first peak of the titanium oxide in X-ray diffraction is 0.05-0.15, the content of the magnesium sulfate increases by 6-22% by mass, the pore volume is 0.17-0.40 cc/g, and the specific surface area is 33-100 m2/g.
