ABSTRACT:
The invention relates to a method for production of a zeolite layer on a substrate containing metal, comprising the following method steps: production of an aqueous suspension, comprising several components, one component comprises at least one cross-linking element from the third, fourth or fifth main group of the periodic table, the substrate containing metal comprises at least one of the cross-linking elements, introduction of the substrate containing metal to the aqueous suspension, heating the aqueous suspension and the substrate containing the metal present therein for the in-situ crystallisation of a zeolite layer on the substrate containing metal, whereby the cross-linking elements in the substrate containing metal are extracted and included in the zeolite layer, a cross-linking element present in the suspension for formation of the zeolite layer is present at a concentration so low that a crystallisation in the suspension is largely or completely avoided and said element is principally provided by the substrate.
