摘要： A honeycomb catalyst for effecting catalytic reduction and removal of nitrogen oxides in waste gas in the presence of ammonia, which homeycomb catalyst (I) contains a catalytically active substance comprising 60 to 99.5% by weight of a binary oxide containing titanium and silicon and 40 to 0.5% by weight of the oxide of at least one metal selected from the group consisting of vanadium, tungsten, molybdenum, copper, manganese, cerium, and tin, (II) possesses an opening ratio in the cross section of said catalyst in the range of 80 to 90%, (III) has a thickness of partition walls separating through holes in the range of 0.2 to 0.8 mm, and (IV) possesses pores comprising substantially two independent pore groups each of a uniform pore diameter, such that the pore volume occupied by one pore group having a pore diameter in the range of 0.01 to 0.03 .mu.m accounts for a proportion in the range of 50 to 80% of the total pore volume and the pore volume occupied by the other pore group having a pore diameter in the range of 0.8 to 4 .mu.m accounts for the proportion of the range of 10 to 30% of the total pore volume.
