ABSTRACT
Metal Organic Frameworks (MOF) are three dimensional organic-inorganic hybrid crystalline materiais where a metal containing inorganic cluster is coordinated to a polydentate organic ligand. MOF-5 consists of Zn40 inorganic moiety, that acts as secondary building unit, coordinating to benzene 1,4-dicarboxylate, a bidentate ligand that acts as spacers, to form a three dimensional structure. We report the synthesis of MOF-5 using zinc nitrate and terephthalic acid as precursors dissolved in dimethyl formamide. The synthesized MOF-5 has been characterized using Fourier Transform Infrared Spectroscopy, X-ray diffractometry, Thermal analysis, Scanning Electron Microscopy and Transmission Electron Microscopy. Surface morphology reveals well-ordered structures with large number of pores in meso-scale. Adsorption capability towards vapours and gases has been studied using ethanol and CO2 as the model vapours using a chemi-resistive approach. Present results indicate that MOF-5 is a promising candidate for CO2 sequestration and gas storage.
