摘要: There is provided a denitration catalyst excellent in denitration activity and durability in a high temperature region, for catalytically reducing NOx in an exhaust gas using a reducing agent such as ammonia. This denitration catalyst is (1) one containing a titanium-tungsten oxide obtained by coprecipitating a soluble titanium compound and a soluble tungsten compound from an aqueous medium under the conditions of a temperature of 60.degree. C. or less and a pH of the range of 5 to 8, and drying and calcining to coprecipitate formed; or (2) one comprising said titanium-tungsten oxide (component A), and an oxide of at least one element (component B) selected from the group consisting of cerium (Ce), lanthanum (La), praseodymium (Pr), neodymium (Nd), nickel (Ni) and tin (Sn).
