Supported zeolite and MOF molecular sieve membranes – Preparation, characterization, application
Institute of Physical Chemistry, Leibniz University Hannover, Hannover, Germany
Despite the simplicity of the concept of a zeolite or MOF molecular sieve membrane, the practical realization of the concept turned out more difficult than expected. Despite much progress in the development of MOF and zeolite molecular sieve membranes, their performance is still not sufficient for an industrial application. By simple chemical modifications of the macro porous ceramic supports, the growth of the zeolite or MOF layer on the support can be facilitated.
There are three main mechanisms that help to grow perfect MOF and zeolite layers on supports if their surfaces are modified by suitable chemical treatment:
Coating of the support surface with a seed layer of nano-zeolites or nano-MOFs facilitates the growth of a thin continuous layer.
Since the macromolecular zeolite and MOF precursors in the synthesis solution are negatively charged, a positive or at least neutral surface charge (zeta potential) facilitates nucleation and gel formation on the surface.
Short chain hydrocarbons turned out as suitable linker molecules with one end covalently bound to the support and with the other end anchored to the molecular sieve zeolite or MOF layer.
