Synthesis of porous materials for cooling and gas storage applications

Metal organic frameworks (MOFs) are porous three dimensional structures formed by inorganic connectors such as chromium and organic linkers such as terephthalic acid. MOFs are studied as their properties make them suitable for use in various applications such as gas storage. MOFs can be used in Adso...
