    摘要: A catalyst for the selective reduction of nitrogen oxides to nitrogen in the presence of ammonia in the form of composite bodies formed from a mixture of anatase (5 to 40% by weight), a zeolite (50 to 90%), a bond material (0 to 30%, and, optionally, promoter selected from oxides of vanadium, molybdenum, and copper, in the amount of at least 0.1% by weight.
