摘要：
A catalyst for removing nitrogen oxides in an exhaust gas, said catalyst containing a first group of many pores having a diameter of 1.times.10.sup.2 .ANG. to less than 1.times.10.sup.3 .ANG. and a second group of many pores having a diameter of 1.times.10.sup.3 .ANG. to 1.2.times.10.sup.5 .ANG., the pore volume of the first group being at least 10% based on the total pore volume of the first group and the second group, and said catalyst comprising titanium and at least one metal selected from molybdenum, tungsten and vanadium as metal elements of catalytically active ingredients.
