abstract = {Gas separation membranes can play a huge role in the future
as a separation technology for hydrogen due to its
poten-tial application as an environmentally friendly energy
storage- or as a propulsion system for vehicles. Natural
gasstreams are considered as a means of transportation for
hydrogen as long as a suitable technology can be used
toseparate hydrogen from the rest of the gas at the end of
the process. Membrane technology appears as a
promisingsolution to this.Interesting membrane materials,
that can achieve the goal of selective H2/CH4 and H2/N2 gas
separations, are 2D-basedzeolite membranes thanks to their
defined pore aperture, and high flux due to their low
thickness [7, 9]. An interesting2D zeolite for the
separation of H2 from bigger gas molecules, such as CH4 or
CO2, is the titanosilicate zeolite JDF-1 dueto the small
pore aperture in the range of the hydrogen molecule [6].
Only a few works in the literature address the useof this
specific zeolite [2, 5, 6]. Most of them focus on mixed
matrix membrane (MMM) preparation by
impregnation/in-filtration of the 2D zeolite and related
nanosheet in a polymer matrix. Such preparation leads to the
formation of com-posite membrane materials with aggregated
zeolite nanomaterial in the polymer matrix. Despite their
impressiveH2/CH4 selectivity of up to 128 [2] such MMMs
exhibit inherent limitations such as their susceptibility to
plasticization[3] and have usually a far bigger thickness up
to the magnitude of several microns [1, 4, 8].In this work,
a new generation of 2D-based zeolite membranes made of
titanosilicate nanosheets was developed directlyon porous
ceramic supports (Fig. 1). The preparation of these
membranes requires the controlled deposition ofnanosheets
followed by the in-situ surface polymerization of a thin
polyimide network to cover the defects and enhancethe
separation performance of the membrane. Relevant
characterization methods were deployed to investigate
themorphology and composition of the membrane and the
separation performance was investigated using gas
permeationmeasurements under pressure gradient.},
