Title
(EN) METHOD OF PRODUCING SEPARATION MEMBRANE
Abstract
(EN)

There is provided a method of producing a separation membrane in which a zeolite membrane is formed on an inorganic oxide porous substrate. The substrate has amorphous SiO2 as a main component of a zeolite formation portion of the substrate, the method includes: a first step of forming a zeolite seed crystal and an alkaline component including a structure directing agent on a surface of the substrate; and a second step of treating a formed product obtained in the first step under a heated steam atmosphere, and the zeolite membrane is formed on the surface of the substrate.
