Advanced synthetic routes of metal organic frameworks and their diverse applications

Abstract

Metal-organic frameworks (MOFs) are crystalline materials characterized by their porous structures, formed through coordination bonding between metal ions/clusters and multidentate organic linkers. MOFs have emerged as a significant class of materials with applications in energy storage, CO2 adsorption, and catalysis. This study serves as a brief introduction to the currently available synthesis methods of MOFs, aimed at acquainting beginners in the field of chemical engineering with the ongoing developments in MOF research. The discussed synthesis methods encompass traditional solvothermal/hydrothermal approaches, microwave synthesis of MOFs, one-pot synthesis, MOF nanocomposites, isothermal synthesis, and fluid-fluid synthesis. Notably, the MOF/NH2/Fe3O4 combination exhibited enhanced adsorption capacity of 618 mg/g and retained an efficiency of over 90 %. This study displays a valuable technique for designing functional MOF hybrid composites. By combining MOFs with specific materials, numerous advantages can be achieved in the newly created compounds (MOF composites), including synergistic effects beneficial in catalytic applications, and overcoming the challenges associated with using bare MOFs.
