The review represents a brief analysis of the known methods for the preparation of zeolite membranes with a continuous selective layer and zeolite crystals embedded in their matrix. The principles of separation on zeolite membranes and the fields of application of these materials are discussed. Some examples of the separation of substances and membrane catalysis on zeolite membranes are given to confirm their high efficiency. Along with the discussion of published data, the authors present their own results.
