AbstractMetal-Organic Frameworks (MOFs) are a new class of hybrid inorganic - organic materials. They are important in gas storage and purification, separation, catalysis, biomedical and various other possible applications. The synthesis of MOFs is frequently performed by solvothermal method. The synthesized MOFs are characterized with various techniques: X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), N2-Adsorption and Scanning Electron Microscopy (SEM). Following the room temperature method we synthesized different MOFs from different metal salts and different linkers. Based on such synthesis, sorne commonly known MOFs (MOF-2, MOF-74 and HKUST-1) were synthesized. These MOFs have been investigated for numerous applications, including ammonia removal. A turning point in the synthesis of MOFs was investigated by the use of linker salt, disodium terephthalate (Na2BDC) as linker source. One such practica} finding was the room temperature synthesis of the archetype MOF called MOF-5 and MIL-53(Al). In particular, MIL-53 (Al) was synthesized at room temperature and using water as a solvent for the first time. The method circumvents the harsh condition in the synthesis of MOFs; high temperature, longer reaction time and the use hazardous solvents. In addition, the method is relevant in the generation of MOFs with important textural properties, eliminates the production of corrosive chemicals and uses water as a solvent. The room temperature synthesis can be adapted in the synthesis of both the known MOFs and MOFs which are not still investigated under envi ronmentall y benign conditions.
