At Fraunhofer IKTS zeolites are synthesized and characterized in powder form or as layers for use as membranes. Zeolite membranes can be used, for example, for energy and resource-efficient gas separation. The size of the gas molecules is below 1 nm, which places special demands on the membrane layer. It should be free of defects and have a high permeance combined with high permselectivity. The separation of the components can be achieved by molecular sieving and/or adsorption effects. In particular the high specific surface area also makes zeolites attractive for use in catalysis processes or in heat storage systems.
