Abstract

The present invention relates to a method for preparing a hydrogen separation membrane capable of preventing the plating of Pd inside a porous support and a porous shielding layer when a separation membrane is prepared; a hydrogen separation membrane prepared therefrom; and a use thereof. In addition, the present invention relates to a device for preparing a hydrogen separation membrane; and a method for preparing a hydrogen separation membrane using the device, and in particular, relates to a device for preparing a hydrogen separation membrane capable of stably growing a Pd-containing separation membrane for hydrogen gas separation as a plating solution grows from the upper surface of a porous support to a uniform thickness by simply shielding the lower surface of the porous support when a hydrogen separation membrane is prepared using an electroless plating method. Furthermore, the present invention relates to a device for preparing a hydrogen separation membrane, and in particular, relates to a device for preparing a hydrogen separation membrane capable of stably growing a composite membrane for hydrogen gas separation as a plating solution grows from the top of a porous support to a uniform thickness by simply shielding the bottom of the porous support.

Dependent claims

A method for preparing a hydrogen separation membrane comprising:

a first step of preparing a porous support;
a second step of preparing a Pd-containing layer comprised of Pd-containing particles on a first surface of the porous support directly or on a porous shielding layer located on the first surface of the porous support;
a third step of introducing a sealing layer that blocks the absorption of an electroless plating solution on a second surface of the porous support;
a fourth step of forming a Pd-containing dense membrane from the Pd-containing particles of the Pd-containing layer by immersing the porous support provided with the Pd-containing layer on the first surface and the sealing layer on the second surface in a Pd-containing electroless plating solution;
and
a fifth step of removing the sealing layer from the porous support.
