The use of a metal–organic framework (MOF) as a support for the in situ immobilization of enzymes was explored. The MOF support, a Basolite F300‐like material, was prepared from FeCl3 and the tridentate linker trimesic acid. Immobilization of alcohol dehydrogenase, lipase, and glucose oxidase was performed in situ under mild conditions (aqueous solution, neutral pH, and at room temperature) in a rapid and facile manner with retention of activity for at least 1 week. The catalytic activities of lipase and glucose oxidase were similar to the activities of the free enzymes; with alcohol dehydrogenase, there was a substantial decrease in activity on immobilization that may arise from diffusion limitations. The approach demonstrates that a MOF material, prepared from cheap and commercially available materials, can be successively utilized to prepare stable and catalytically active biocatalysts in a rapid and facile manner.

“…The 6,8-connected Zn-TBCPPM MOF based on the tetrakis {3,5-bis[(4-carboxyl)phenyl]phenyl}methane (TBCPPM) bridging ligand shows an exceptionally high gas uptake capacity at 298 K with an excess CH 4 uptake of 17.5 wt% at 35 bar and 27.6 wt% at 80 bar. 23 Unlike hydrogen, the interactions between methane and the aromatic MOF frameworks are strong enough for practical storage applications. 21c Rigorous investigation toward highly robust and affordable MOFs for large scale on-vehicle methane storage is urgently needed.…”

Metal-organic frameworks (MOFs), also known as coordination polymers, represent an interesting class of crystalline molecular materials that are synthesized by combining metal-connecting points and bridging ligands. The modular nature of and mild conditions for MOF synthesis have permitted the rational structural design of numerous MOFs and the incorporation of various functionalities via constituent building blocks. The resulting designer MOFs have shown promise for applications in a number of areas, including gas storage/separation, nonlinear optics/ferroelectricity, catalysis, energy conversion/storage, chemical sensing, biomedical imaging, and drug delivery. The structure-property relationships of MOFs can also be readily established by taking advantage of the knowledge of their detailed atomic structures, which enables fine-tuning of their functionalities for desired applications. Through the combination of molecular synthesis and crystal engineering MOFs thus present an unprecedented opportunity for the rational and precise design of functional materials.

“…Gas adsorption and separation [1], gas storage [2], chemical sensing [3], drug delivery [4] and heterogeneous catalysis [5] are the most popular fields of metal-organic framework (MOFs) utilization. Among all classified MOF structures (over 60,000 reported in Cambridge Crystallographic Data Centre, but many of them are repeated), there are some that attract special attention owing to very high-if not outstanding-surface area, chemical properties or thermal and chemical resistance.…”

The Impact of Synthesis Method on the Properties and CO2 Sorption Capacity of UiO-66(Ce)

et al. 2019

A series of cerium-based UiO-66 was obtained via hydrothermal and sonochemical methods, using the same quantities of reagents (cerium ammonium nitrate (CAN), terephthalic acid (H2BDC)) and solvents) in each synthesis. The impact of synthesis method and metal to linker ratio on the structural and textural properties of obtained UiO-66(Ce), as well as their composition in terms of Ce4+/Ce3+ ratio, structure defects resulting from missing linker, and CO2 adsorption capacity was discussed. By using typical characterization techniques and methods, such as XRD, N2 and CO2 sorption, TGA, XPS, and SEM, it was shown that the agitation of reacting mixture during synthesis (caused by stirring or ultrasounds) allows to obtain structures that have more developed surfaces and fewer linker defects than when MOF was obtained in static conditions. The specific surface area was found to be of minor importance in the context of CO2 adsorption than the contribution of Ce3+ ions that were associated with the concentration of linker defects.
