Abstract: Disclosed is a method for producing catalytically active multielement oxide materials containing at least one of the elements Nb and W as well as elements Mo, V, and Cu. According to the inventive method, an intimate dry mixture containing ammonium ions is produced and is thermally treated at a raised temperature in an atmosphere that is low in molecular oxygen. A partial quantity of the ammonium ions contained in the intimate dry mixture is decomposed so as to release ammonia while the oxygen concentration of the thermal treatment atmosphere is increased in the course of the thermal treatment.
