The present invention is directed to a process for the production of ion-exchanged (metal-doped, metal-exchanged) Zeolites and Zeotypes, In particular, the method applied uses a sublimation step to incorporate the ion within the channels of the Zeolitic material. Hence, according to this dry procedure no solvent is involved which obviates certain drawbacks connected with wet exchange processes known in the art.
