Abstract: The invention relates to a heterogeneous catalyst containing iron and copper and to a method for the production thereof comprising the following steps: I. Pyrolyzing gaseous iron pentacarbonyl to yield carbonyl iron powder having spherical primary particles, II. Treating the carbonyl iron powder yielded in step I with hydrogen, wherein the metal spherical primary particles at least partially agglomerate, III. Surface oxidation of the iron particles from step II (agglomerates = secondary particles, and optionally remaining primary particles), forming iron oxide, IV. Bringing the particles from step III in contact with an aqueous solution of a copper compound, V. Drying in the presence of oxygen and subsequent calcination in the absence of oxygen, wherein copper compounds containing oxygen initially result on the particles, which compounds then react with the iron oxide forming a mixed oxide of the formula Cu
