A denitrizing catalyst which comprises: (a) an alkali metal oxide or an alkaline earth metal oxide in amounts of 50-90 % by weight as oxides; (b) at least one metal oxide selected from the group consisting of Co3O4, Cu2O, Cr2O3, Mn2O3, NiO, PbO, Bi2O3, MoO2, Al2O3, SiO2, ZrO2, Fe2O3, TiO2, WO3, MoO3, SnO2 and ZnO in amounts of 5-50 % by weight as oxides; and (c) at least one metal or at least one oxide of metals selected from the group consisting of Ru, Rh, Pd, Ag, Pt and Au in amounts of 0.01-10 % by weight as metals. Nitrogen oxides contained in waste gases are denitrized effectively by putting the gases into contact with the catalysts in the absence or presence of carbon monoxide as a reducing agent.
