aThe latest developments in zeolite membranes are reviewed, with an emphasis on the synthesis techniques, including seed assembly and secondary growth methods. This review also discusses the current industrial applications of zeolite membranes, the feasibility of their use in membrane reactors and their hydrothermal stability. Finally, zeolite membranes are compared with metal-organic framework (MOF) membranes and the latest advancements in MOF and mixed matrix membranes are highlighted.

“…Chiral MOF catalysts with uniform active sites for enantioselective reactions have been developed based on functionalized chiral molecular (pre)catalysts [21][22][23][24][25][26][27][28][29][30] . In a handful of latest studies, the resolution of enantiomers (racemic alcohols and sulphoxides) with chiral MOFs via chromatography [31][32][33][34] , crystallization [35][36][37][38][39][40] and membrane 41,42 has been reported, but only few exhibit good chiral separation performance.…”

Engineering chiral porous metal-organic frameworks for enantioselective adsorption and separation

The separation of racemic molecules is of substantial significance not only for basic science but also for technical applications, such as fine chemicals and drug development. Here we report two isostructural chiral metal-organic frameworks decorated with chiral dihydroxy or -methoxy auxiliares from enantiopure tetracarboxylate-bridging ligands of 1,1 0 -biphenol and a manganese carboxylate chain. The framework bearing dihydroxy groups functions as a solid-state host capable of adsorbing and separating mixtures of a range of chiral aromatic and aliphatic amines, with high enantioselectivity. The host material can be readily recycled and reused without any apparent loss of performance. The utility of the present adsorption separation is demonstrated in the large-scale resolution of racemic 1-phenylethylamine. Control experiments and molecular simulations suggest that the chiral recognition and separation are attributed to the different orientations and specific binding energies of the enantiomers in the microenvironment of the framework.

“…QCM experiments with homochiral SURMOFs of type Zn 2 (cam) 2 (dabco) (cam = camphoric acid) give evidence for the selective enantiomeric loading properties (Figure 17.10) [62]. Though this has proven the potential of SURMOFs for enantiomeric separation application, QCM per se is not sensitive to the sample chirality, and no information about the separation efficiency can be obtained when loading a racemic mixture.…”

“…The difference in the absolute adsorption values for the two samples may be due to a slight difference in the total amount of SURMOF deposited on the QCM substrate surface. (Reprinted from[62]. Copyright 2012, with permission from Wiley-VCH.…”
