Abstract (en)

[origin: WO2006032230A1] The invention relates to a method for producing a device for gas separation, said device comprising a layer system wherein a functional layer consisting of Ti0<SUB>2</SUB> and/or Zr0<SUB>2</SUB> having an average pore diameter of less than 1 nm is applied to at least one side of a carrier layer that is porous throughout. Said carrier layer is preferably between 100 ?m and 1 mm thick and comprises continuous pores with an average pore diameter in the ?m range. The functional layer which is applied directly or by means of at least one intermediate layer comprises continuous pores with an average pore diameter of less than 1 nm, especially less than 0.8 nm. The functional layer can advantageously be embodied as a graduated layer. The invention is especially characterised by the symmetrical structure of the device, in which functional layers are applied to both sides of the carrier layer, optionally by means of respectively at least one intermediate layer.
