Hybrid materials based MOFs

For more efficient utilization of MOFs sorbents, several hybrid systems based on MOFs with other solid sorbents have been investigated in the literature. The objective of having hybrid materials is to utilize the synergism between the two sorbents and therefore ultimately improve the overall performance in C02 separation. Moreover, sorbents such as activated carbons, graphenes, and CNTs provide the added feature of high surface area and easily functionalized sites which contribute to the tuning of the final properties of the composite... 

MOFs are highly crystalline inorganic-organic hybrid materials. The conceptual approach for synthesizing these materials is based on the self-assembly into a three-dimensional structure of cationic systems, acting as nodes. 

Al-based porous frameworks were also reported to moderately conduct protons above lOO C through the incorporation of imidazole (Im) within the pores. A higher proton-conductive MOF was obtained by introducing adipic acid in a layered oxalate-bridged framework (NH4)2[Zn2(ox)3]-3H20. Also, hybrid materials comprising a MOF and POMs were investigated. ... 

The past nearly six decades have seen a chronological progression in molecular sieve materials from the aluminosilicate zeolites to microporous silica polymorphs, microporous aluminophosphate-based polymorphs, metallosilicate and metaHo-phosphate compositions, octahedral-tetrahedral frameworks, mesoporous molecular sieves and most recently hybrid metal organic frameworks (MOFs). A brief discussion of the historical progression is reviewed here. For a more detailed description prior to 2001 the reader is referred to [1]. The robustness of the field is evident from the fact that publications and patents are steadily increasing each year. 

Hybrid membrane or MMM using MOFs as the filler material is another option for the application of MOFs in membrane separation. Adams et al. [118] reported an MMM comprised of poly (vinyl acetate) (PVAc) and a MOF composed of copper and bdc ligand (Cu-bdc), which exhibited an increased selectivity for many gases, including CO2 upon inclusion of the MOF compared with the pure PVAc membrane. Ordonez et al. reported the ZIF-based polymer MMM using ZIF-8 as the filler phase and Matrimid as the polymer phase, respectively as shown in... 

Thus, concurrently with other CD-based materials for catalysis (such as CD-based metallic nanoparticles [65], 3-CD-silica hybrid [66], and more recently CD-based metal-organic frameworks (MOF) [67]), CD-based polymers also appear to be very effective materials to improve catalytic performance in aqueous media.
