Patent ID: 8053032

Claim:
Method for the production of a zeolite layer on a substrate containing aluminum, comprising the following method steps: 1.1 production of an aqueous suspension comprising several components, wherein 1.2 one component comprises at least one cross-linking element from the third, fourth or fifth main group of the periodic table; and 1.3 the substrate containing aluminum comprises at least one of the cross-linking elements; 1.4 introduction of the substrate containing aluminum into the aqueous suspension; 1.5 heating the aqueous suspension and the substrate containing aluminum present therein for the in-situ crystallization of a zeolite layer on the substrate containing aluminum, characterized in that 1.6 at least one of the cross-linking elements present in the aqueous suspension is deficient with respect to the zeolite formation process and the final structure of the zeolite, wherein the molar ratio of the deficient cross-linking element(s) present in the aqueous suspension to the sum of all cross-linking elements present in the aqueous suspension is less than 0.5, 1.7 the deficiently provided cross-linking element(s) is/are extracted from the substrate containing aluminum and included in the zeolite layer; and 1.8 one cross-linking element is phosphor, which is present in the aqueous suspension.
