Description:
The zeolite-to-zeolite transformation with layered precursors as nanoscale building blocks has been identified as one of the most promising strategies for the preparation of novel 2D and 3D materials. Advances in the synthesis of new zeolites with the rational control of their composition, morphology and functionalities have revealed considerable potential for their application in adsorption, separation and catalysis. An alternative, environment-conscious separation technique (with respect to energy-intensive cryogenic distillation) is the kinetic separation of hydrocarbons on small-pore zeolites with 8MR channels. Recent research has shown that the nominal crystallographic pore aperture size may not be decisive factor and that the lattice flexibility can have a significant impact on diffusivity assessment. This project focuses on this phenomenon promoted by zeolite flexibility and on predicting flexibility effects for zeolite frameworks with nanoscale architecture. Progress in this direction can lead to the discovery of new materials for efficient molecular separation.
