Soluble Enzymes

MOFs are porous materials with adjustable porosity ensuing a tenable surface area and stability. MOFs consist of metal containing joint where organic ligands are linked with coordination bonding rendering a unique architecture favouring the diverse applications in attachment of enzymes, Chemical catalysis, Gases storage and separation, biomedicals. In the past few years immobilization of soluble enzymes on/in MOF has been the topic of interest for scientists working in diverse field. The activity of enzyme, reusability, storage, chemical and thermal stability, affinity with substrate can be greatly improved by immobilizing of enzyme on MOFs. Along with improvement in enzymes properties, the high loading of enzyme is also observed while using MOFs as immobilization support. In this review a detail study of immobilization on/in Metalorganic Frameworks (MOFs) have been described. Furthermore, strategies for the enzyme immobilization on MOFs and resulting in improved catalytic performance of immobilized enzymes have been reported.

Combustion Processes

Air pollution is an epochal concern, particularly in urban areas, and is linked to combustion processes 1 . The emission of nitrogen oxides (NOx) constitutes a critical environmental problem, and it can affect severely human health2,3,4 . At ambient temperature and pressure NOx decomposition is thermodynamically favoured; however, this process is kinetically inhibited, owing to a high activation energy5,6 . To date, no reported catalysts have had the required properties to lower the activation energy of this process without the help of coreacting agents and high temperatures7,8,9 . Here, we show that NO conversion to molecular nitrogen can be achieved at room temperature in the presence of O2 and H2O vapour, and in the absence of any further reducing agent, using iron-based Metal-Organic Frameworks (MOFs). Further, we demonstrate that MOFs work similarly to enzymes, but are stable in environments unfriendly to living matter. These findings open large perspectives on the solution of stringent problems in chemistry, such as the removal of pollutants or the activation of highly stable molecules.<br>

Elllipse-like europium-based metal–organic framework (MOF) has been successfully synthesized on a large scale through an efficient and facile direct precipitation method. The composition and structure of the samples were well characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), elemental analysis (EA), scanning electronic microscope (SEM), and photoluminescent spectra (PL), respectively. The speculated molecular formula of the Eu-based MOF is [Eu(MA)1.5(H2 O)2 ]•5H2 O. The experimental result demonstrate that these elllipse-like with diameter of about 3-5 μm are assembled of a series of dense nanoplate. The effect of MA/ KOH molar ratio and surfactant on the morphologies and sizes of the final microcrystals were studied. Moreover, the morphology-dependent photoluminescence properties were also investigated in detail. This preparation route is very prospective for the synthesis of the other nano/micro-sized materials due to its simple synthesis method.

Employing Metalorganic frameworks (MOFs) as precursor, a series of CuO/CeO2 catalysts with welldispersed copper species were synthesized and applied for preferential CO oxidation in H2rich stream. The high activity of the CuO/CeO2 catalysts indicated that MOFs precursor played a key role in improving the dispersion of metal active sites.
