      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.},
