Eight laboratories specializing in ceramic membrane science and/or in catalysis have formed a cooperative network to study and develop advanced gas separation membranes and also membrane reactors which combine reaction/separation processes. Both types of membranes are of major industrial and environmental importance. The laboratories will in collaboration develop a series of new ceramic membranes which will, directly or with modification, provide a range of advanced gas separation and catalytic membranes with unsurpassed chemical and thermal properties, ideally suited to advanced industrial and environmental applications in the coming years. A new generation of high-temperature stable ceramic membranes of porous (anodic) alumina, prepared in Glasgow and Minsk, will be further modified by deposits of thin active layers of catalysts in the form of finely divided metals and active oxides. The resulting membranes are expected to be usable at exceptionally high temperatures and in some cases combine catalysis with the separation of products in a single step, giving unsurpassed efficiencies. In a parallel development using alumina and other ceramic membranes modifications will be made to provide new selective membranes for gas separations. The following research will be performed in the network: investigation of the mechanism of anodic alumina (AA) growth and the mechanism of the appearance of secondary porosity; variation of mechanical properties with conditions of anodization and post-treatments; increasing flexibility and microhardnesses of thin AA films; creation of thin layers (10 - 100 nm) of oxides and/or metals on polycrystalline anodic alumina films by sputtering and vacuum deposition; investigation of adhesion properties, high temperature stability; uniformity of composition and morphology of thin layers; creation of multi-layer systems based on anodic alumina with controlled pore size distribution for each layer; preparation of catalyst-membranes for processes of hydrogenation and dehydrogenation based on M films and other types of ceramic membranes; preparation of membranes for gas separation based on polycrystalline AA and other oxides; modification of morphology and surface properties of catalyst membranes and membranes for gas separation; functional characterization of catalyst membranes and membranes for gas separation: catalytic properties - hydrogenation and dehydrogenation, IR spectroscopy of surface, temperature programmed de-absorption, reduction and temperature-resolved absorption, electrochemical properties of surface, permeability, gas separation; material science characterization of catalyst membranes and membranes for gas separation: phase composition and transformation, morphology of support and active layers, and pore size distribution.
