PROBLEM TO BE SOLVED: To provide a method of manufacturing for a denitration catalyst capable of removing NOx, excellent in durability and with the oxidation of sulfur dioxide to sulfur trioxide strictly inhibited. SOLUTION: The denitration catalyst containing the oxides of silicon, titanium, tungsten and vanadium for removing NOx in an exhaust gas is manufactured by the following method. Namely, a vanadium compound is added to a multiple oxide (WO3-SiO2) of tungsten and silicon prepared by previously depositing tungsten on the oxide of silicon. |
