Abstract: A method for fabricating a high-density zeolite membrane structure is described. The method includes the step of combining (i) a mineral zeolite material; (ii) at least one cement precursor; and (iii) an organic binder, with an aqueous component, to form an aqueous composite zeolite composition. The zeolite composition is then applied on a surface of a scaffold formed from a porous, metal oxide material. The zeolite composition is dried, and then heated under conditions to form a metal oxide-zeolite composite layer. This layer is exposed to a phosphate composition, under conditions sufficient to reduce the porosity to a level no greater than about 10%. A high-density zeolite cement composite membrane structure results. Related methods for separating hydrogen from a fluid stream, using the membrane structure, are also disclosed.
