Abstract:
A process for producing a zeolite film is provided in which seed crystals thinly adhere to the surface of a support to form a thin and even zeolite film having fewer defects than conventional zeolite films. Also provided is a zeolite film obtained by the producing process. The process for producing the zeolite film comprises: a particle adhesion step of allowing a slurry, where zeolite particles which become seeds are dispersed, to flow down on the surface of a base material by the self-weight of the slurry, so that the zeolite particles adhere to the base material; and a film formation step of immersing the base material, to which the zeolite particles adhere, into a sol to carry out hydrothermal synthesis, thereby forming the zeolite film on the base material.
