                      nano-structured porous SiO$_{2}$-membrane layers with porous
                      ceramic and metallic substrates were studied aiming at their
                      applications for the carbon dioxide separation in the
                      pre-combustion systems in fossil-fired power plants. Since
                      the thin membrane layers demand a mechanically robust
                      substrate material, alumina materials as promising
                      substrates with different porosity and pore sizes were
                      characterized with respect to their mechanical properties.
                      In the asymmetric gas separation membrane, the porosity of
                      the substrate should be maximized in order to minimize its
                      resistance against permeate gas. However, an increase in
                      porosity usually reduces Young’s moduli and fracture
                      stress of the substrate material. In this study, two types
                      of alumina substrate materials with similar porosity but
                      micro-porous and nano-porous microstructure, respectively,
                      were investigated in order to assess the influence of the
                      pore size on mechanical properties. As an alternative
                      substrate material, porous metallic Intermediate Temperature
                      Metal (ITM) coated with $\gamma$-Al$_{2}$O$_{3}$ interlayer
                      and functional SiO$_{2}$-membrane was also investigated with
                      respect to its mechanical properties. An acoustic emission
                      test was adopted to determine the correlation deformation-
                      failure behaviour of this composite membrane system. Another
                      focus of the work was a determination of the gas
                      permeability of various gases through SiO$_{2}$ and
                      amino-modified SiO$_{2}$ membranes, in which the adopted gas
                      systems were single gas, binary gas mixtures and binary gas
                      mixtures plus water vapour. The gas transport mechanism was
                      investigated via the single gas permeation tests. The
                      application of membranes in the flue gas was simulated by
                      permeation tests with binary gas mixture plus water vapour.
                      Meanwhile, the enhanced affinity of CO$_{2}$ towards
                      amino-modified SiO$_{2}$- membranes with and without water
                      vapour was also investigated via annealing tests and
                      infrared spectroscopy. Furthermore, the effect of mechanical
                      pre-deformation onto the membrane system was also
                      investigated via the permeation tests. A change of gas
                      transport mechanism through the membranes was analysed by
                      comparing the permeation results of non-deformed and
                      predeformed specimens with metallic substrate.},
