Method for producing a gas separation membrane

The method according to claim, 1 wherein the porous support (i) comprises materials resistant to sintering temperatures and compatible with the materials of the functional separation layer (ii).

The method according to claim, 1 wherein the porous support (i) is constituted by materials that are selected from the group consisting of magnesium oxide, aluminum and magnesium spinels, cerium oxide doped with at least one lanthanide metal, zirconium oxide doped with at least one of the following elements:

• Y, Mg, Se or a lanthanide metal;
• titanium oxide, aluminum nitride, refractory alloys/superalloys, clay-based materials or silicates of aluminium, magnesium silicate, iron, titanium or alkaline or alkaline-earth elements, iron perovskites and combinations thereof.

A ceramic membrane obtained by the method comprising:

• deposition on a porous support (i), by means of an inkjet printer, of at least one functional separation layer (ii) comprising at least two inks and
• at least one thermal treatment, which produces sintering of the functional separation layer (ii) layer, and
• deposition of at least one porous catalytic activation layer (iii) on the functional separation layer (ii).
