The present invention relates to a method for producing a precursor of a supported platinum catalyst. To provide a method for producing a platinum catalyst precursor, by means of which supported platinum catalysts can be produced which have a relatively high activity, a method is proposed, comprising the steps of: a) impregnating an open-pored support material with platinum sulphite acid; b) calcining the impregnated zeolite material under a protective gas.
