Metal Organic Framework (MOF) Materials: Synthesis and Characterization Study

Metal Organic Frameworks (MOFs) are microporous materials with crystalline structure composed of organic and inorganic species. MOF materials have gained popularity among researchers due to their potential for gas capture, separation, catalysis and other applications. Zn(BDC)(TED)0.5 is one of the M...

description Metal Organic Frameworks (MOFs) are microporous materials with crystalline structure composed of organic and inorganic species. MOF materials have gained popularity among researchers due to their potential for gas capture, separation, catalysis and other applications. Zn(BDC)(TED)0.5 is one of the MOFs with characteristic such as high hydrophobicity and large channels properties. The current project emphasizes on synthesis and characterization of Zn(BDC)(TED)0.5. Thus, the effect of synthesis conditions on the formation of the MOFs was studied.
