Method for the production of form-selective catalysts and use thereof

A process for manufacturing zeolite catalysts containing subgroup metals by hydrothermal synthesis with subsequent calcination, characterized in that the subgroup metals in the form of complexes of the general formula

• [metalz(CO)a(CN)b(CNR)c(X)d(Y)e]n− or n+
• with z≧1,
• R=alkyl chain with 1 to 10 carbon atoms,
• a, b, c, d and e=0 or a whole number, wherein a, b, c, d and e can be identical or unidentical and the sum of a, b, c, d and e is ≧1,
• n=0 or is a negative or positive whole number and
• X and Y represent a volatile component are introduced to the hydrothermal synthesis of the zeolite catalysts.
