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

The CO2 concentration in the atmosphere is constantly rising mainly through industrial and power plant discharges this has led to urgent calls for strategies to reduce CO2. 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 multifunctionalMOFmaterials. Amine groups being basic in nature have excellent affinity towards acidic CO2 group. Amine functionalized metal organic framework materials have promising tendencies as dry adsorbents for post-combustion CO2 capture, owing to their enhanced CO2 capture capacity. This research work is focused on the synthesis of a new amino functionalized Cu based MOFusing 2-aminoterephthalic as a linker. The structure was confirmed by Single Crystal XRD studies. The Single CrystalXRDstudies reveal that an amine functionalized MOF is prepared which has free -NH2 group aiding in theCO(2) adsorption. The CO2 adsorption study tells us that theMOFexhibits a better CO2 capture tendency of 5.85 mmolg(-1) at 25 degrees C as compare to Cu-BDC MOF.
