Ceramic and hybrid membrane design, characterisation & performance evaluation. Inorganic & composite membranes for gas & vapor separations - Confined systems.

The cluster "Sol-gel and Solutions Chemistry" is specialized in the development of a variety of ceramic, hybrid and composite membrane, either porous or dense, whose composition, design and microstructure have to be controlled. To this end, the cluster develops a body of work around how to develop original membranes by "soft" chemistry (sol-gel process, polyol or solvothermal synthesis, possibly assisted by microwave heating, sonochemistry or original solvents such as supercritical CO2 media). The exploration of innovative characterization methods, specifically adapted to membranes and thin films is another priority of the cluster, carried out in close collaboration with the "plasma" cluster. Target applications for the developed membrane materials mainly involve catalytic and photocatalytic, gas separation/treatment for both energy and environment-related applications as well as water treatment with non-oxide membranes.
