Novel amine functionalized metal organic framework synthesis for enhanced carbon dioxide capture

The CO 2 concentration in the atmosphere is constantly rising mainly through industrial and power plant discharges this has led to urgent calls for strategies to reduce CO 2 . Metal organic frameworks (MOFs), also known as coordination polymers, represent an interesting type of solid crystalline materials that can be straight forwardly self-assembled through the coordination of metal ions/clusters with organic linkers. These unique advantages enable MOFs to be used as a highly versatile and tunable platform for exploring multifunctional MOF materials. Amine groups being basic in nature have excellent affinity towards acidic CO 2 group. Amine functionalized metal organic framework materials have promising tendencies as dry adsorbents for post-combustion CO 2 capture, owing to their enhanced CO 2 capture capacity. This research work is focused on the synthesis of a new amino functionalized Cu based MOF using 2-aminoterephthalic as a linker. The structure was confirmed by Single Crystal XRD studies. The Single Crystal XRD studies reveal that an amine functionalized MOF is prepared which has free –NH 2 group aiding in the CO 2 adsorption. The CO 2 adsorption study tells us that the MOF exhibits a better CO 2 capture tendency of 5.85 mmolg −1 at 25 °C as compare to Cu-BDC MOF.
