ABSTRACT

In this study we try to explore the concept of metal organic frameworks in a holistic context. Metal-organic frameworks (MOFs) obtained much attention because of their unusual

structures and properties as well as their potential applications. The main focus of the research is on the gas storage and its relation with metal organic frameworks. Metal-organic frameworks (MOFs) are a special type of porous material with a number of unique properties, including exceptionally high surface areas, large internal pore volumes (void space) and tunable pore sizes. These materials are prepared through the assembly of molecular building blocks into ordered three-dimensional structures. The bulk properties of the MOF are determined by the nature of the building blocks and, as such, these materials can be designed with special characteristics that cannot be realized in other sorbent materials, like activated carbons. The research also analyzes many aspects of features and industrial applications and tries to gauge its effect metal organic frameworks. Metal-organic frameworks (MOFs) have emerged as a new type of functional materials and have witnessed explosive development and rapid progress over the past 15 years. MOFs, also known as coordination polymers, are highly crystalline inorganic-organic hybrids constructed by assembling metal ions or small metal-containing clusters [known as secondary building units (SBUs)] with multidentate organic ligands (such as carboxylates, tetrazolates, and sulfonates) via coordination bonds. They can be one-, two-, or three-dimensional infinite networks. Of those, three-dimensional MOFs with permanent porosity, which can also be called porous MOFs, are of the greatest interest because the voids inside the frameworks can accommodate guest molecules for a number of applications. Through the judicious selection of the metal ions or SBUs and organic linkers, not only can a variety of topologies and structures be produced, but the pore sizes can be systematically tuned and the pore walls can be functionalized for specific applications in catalysis, sensor, gas storage/separation, etc.. This review will focus on the current status of gas adsorption applications of porous MOFs, including hydrogen storage, methane storage, and selective gas adsorption. Finally the research describes various factors which are responsible for the operation of metal organic frameworks and tries to describe the overall effect of different gas storages on metal organic frameworks.
