<p>A method for producing a catalyst for removing nitrogen oxides which comprises dispersing moist titanium oxide or a dried material therefrom, tungstic acid or a salt thereof, and cerium dioxide to form a sol-like material, mixing the sol-like material with an aqueous medium to prepare a catalyst slurry or paste, and allowing a carrier to carry the slurry or paste thereon, followed by firing. The method prevents Ce oxide from being buried in Ti oxide and achieves the high degree dispersion of Ce oxide on the surface of titanium oxide, the degree being comparable to the case of using an ion exchange zeolite, and also allows the production of a catalyst for removing nitrogen oxides being free from the sintering of titanium oxide, the deterioration of a zeolite due to steam, and the like.</p> |
