The present invention relates to a method for producing a supported catalyst, a catalyst which is obtainable using the method, and use thereof for the partial oxidation or ammoxidation of olefins, in particular for the oxidation of propene to acrolein, of isobutene to methacrolein, and/or the ammoxidation of propene to acrylonitrile. The method according to the invention includes the following steps: a) providing a solution in which precursor compounds of the catalytically active component are essentially completely dissolved in a suitable solvent; b) bringing the solution obtained in step a) into contact with a (chemically) inert, porous support having a specific surface of 1 to 500 m/g; c) heat treatment of the material obtained in step b), in which the precursor compounds of the catalytically active component are converted to their oxides.
