Carrier-supported catalyst on the basis of transition metals for the removal of nitrogen oxides, carbon monoxide and/or organic compounds from exhaust gases, which can be produced by one of: combination a), combination b), combination c) where (a) comprises charging of a carrier with at least one metal complex compound with a plane or nearly plane conformation, and activation of the charged carrier with (i) a gas mixture which contains nitrogen oxide and/or oxygen, at temperatures between room temperature and 500 DEG C., or with (ii) a solution which contains nitric acid and/or an oxidation agent, or (b) comprises charging of a carrier with at least one transition metal oxide or transition metal carbonate, and treatment of the charged carrier with an oxidizing gas mixture, which contains free ligands capable of complex formation, at temperatures between room temperature and 500 DEG C., or c) comprises treatment of at least one transistion metal oxide or transition metal carbonate with a solution which contains nitric acid and/or an oxidation agent, and free ligands capable of complex formation, and charging of a carrier with the treated transition metal oxide or transition metal carbonate, as well as a process for its manufacture and its use for the treatment of exhaust gases.
