摘要： A method of cleaning an exhaust gas containing nitrogen oxides, carbon monoxide and an excess of molecular oxygen, which comprises passing the exhaust gas together with ammonia over a catalyst comprising (A) 60 to 99.9% by weight of a catalytic oxide composed of a titanium containing oxide, (B) 0.1 to 20% by weight of a catalytic oxide composed of at least one metal oxide selected from the group consisting of oxides of copper, manganese and chromium and (C) 0 to 20% by weight of a catalytic oxide composed of at least one metal oxides selected from the group consisting of oxides of vanadium, tungsten, molybdenum, cerium and tin at a temperature of 200.degree. to 500.degree. C.
