“…MOFs, generally, appear to have better compatibility with polymers in mixed matrix membranes compared to zeolites. [109][110][111] However, performance gains have been similarly modest. Even if compatibility is resolved there are other issues like the flux matching requirement which allow only a small fraction of the zeolite/MOF selectivity to be harvested in a mixed matrix setting.…”

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.

“…Most extractor catalytic membranes are dense membranes and the transport mechanism depends on the principle of solution/diffusion through the bulk of the material. The permeation through the membranes implies that the molecule of selected gas or liquid is adsorbed on the membrane surface, and dissolves in the membrane material, then diffuses through the membrane and desorbs on the other side [56].…”

“…The feed was oxygen and hydrogen in excess, they flew to the shell tubular reactor then they flew Figure 5. Schematic drawing for the extractor catalytic membrane function in the esterification reaction [56] through the catalytic membrane in doses. The catalytic layer of the membrane was Pd/SiO2 in the top layer of the membrane, where hydrogen and oxygen react to form H2O2 while the bottom layer of the membrane was titanium silicalite to catalyze the reaction between H2O2 with propylene and produce propylene oxide [59].…”

The development of the chemical industry regarding reducing the production cost and obtaining a high-quality product with low environmental impact became the essential requirements of the world in these days. The catalytic membrane is considered as one of the new alternative solutions of catalysts problems in the industries, where the reaction and separation can be amalgamated in one unit. The catalytic membrane has numerous advantages such as breaking the thermodynamic equilibrium limitation, increasing conversion rate, reducing the recycle and separation costs. But the limitation or most disadvantages of catalytic membranes related to the high capital costs for fabrication or the fact that manufacturing process is still under development. This review article summarizes the most recent advances and research activities related to preparation, characterization, and applications of catalytic membranes. In this article, various types of catalytic membranes are displayed with different applications and explained the positive impacts of using catalytic membranes in various reactions. Copyright

“…It is accepted that the MOF-based mixed matrix membranes (MMMs) [69][70][71][72][73], which refer to the composite membranes with MOF powder fillers dispersed in polymer matrix, possess most promise for practical separation applications. But their permeability is lower compared to the pure MOF membranes caused by the nonporous polymer matrix [74][75][76]. Therefore, the continuous MOF membranes become the promising candidates which could achieve both high permeability and excellent selectivity.…”
