A review on metal-organic framework: synthesis, properties and application

Abstract

Metal organic framework is a class of hybrid network of supramolecular solid materials comprised of a large number of inorganic and organic linkers all bounded to metal ions in a well organised fashion. This type of compounds possess a greater surface area with an advantage of changing pore sizes, diversified and beautiful structure which withdrew an intense interest in this field. In the present review article structural aspects; classification; methods of synthesis; various factors affecting the synthesis and stability; properties and applications have been discussed. Recent advances in the field and new directions to explore the future scope and applications of MOFs have been incorporated to provide current status of the field.

Synthesis, characterization, and CO2 adsorption properties of metal organic framework Fe-BDC

“…Using different metal centers and solvents affects the properties such as hardness and stability, degree of crystallinity, etc. [69][70][71] Differences between the synthesis conditions of MIL-101 and MIL-53 synthesized by Cr and Al compared to MIL-101 and MIL-53 synthesized by Fe, such as the reaction temperature (220 C versus 110 C) and solvent (water vs. DMF), may leads to the formation of more stable materials with lower energy levels. On the other hand, the higher stability of MIL-101(Fe)-NH 2 against polar solvents, e.g.…”

Advances in Enzyme and Ionic Liquid Immobilization for Enhanced in MOFs for Biodiesel Production

“…For the electrochemical synthesis of MOFs, metal ions are continuously supplied through anodic dissolution instead of metals salts; they react with the linker molecules and a conducting salt dissolved in the reaction medium [108]. The method was first used for the preparation of HKUST-1 [Cu 3 (BTC) 2 ], which afforded promising results in renewable fuel production [105].…”

“…To improve enzyme stability, the weak interactions can be replaced by covalent interactions between the nucleophiles of the enzymes (free amino acids) and the organic linkers (mainly carboxylate groups) of MOFs to form peptide bonds [106]. Among the strong chemical bonds developed during enzyme immobilization, multipoint covalent attachment between the MOF and functional groups of the enzyme, such as amino, glyoxyl, and epoxy [107], leads to the formation of a rigid backbone that stabilizes the enzyme structure, enhances its resistance to unfolding and denaturation, and reduces enzyme leaching (a common feature of chemisorption) [108]. For example, Candida antartica lipase-B was immobilized by covalent bonding on activated isoreticular MOF-3 by dicyclohexylcarbodiimide with an enzyme loading of 0.18 mg/g, improving the enzymatic activity by up to 103 times compared to that of the free enzyme [120].…”

A Review on Nanocellulose and Its Application in Supercapacitors

“…[129] MOFs are a new class of crystalline porous materials that can be synthesized by combining metal ions with organic linkers or bridging ligands, through conventional synthesis of solvothermal and nonsolvothermal, or assisted synthesis (microwave, electrochemical, sonochemical, ultrasonic, and layer by layer). [130,131] Adding an ordinal number to the acronym MOF represents the specific MOF, such as MOF-74 (Metal Organic Framework-74), MOF-177 (Metal Organic Framework-177), ZIF-8 (Zeolite Imidazolate Framework-8), HKUST-1 (Hong Kong University of Science and Technology-1). [132] As well as having a large surface area and being low-cost to synthesize, MOFs can be processed and tuned to suit the particular application of interest.…”
