Fine Structural Analysis of Solvent Activated Cu-BTC for Carbon Dioxide Capture

Metal organic frameworks (MOFs) are presently under substantial investigation due to their properties and high potential as new class of porous material for carbon dioxide (CO2) capture. Experimentally, Cu-BTC crystalline frameworks with diameter of approximately 6-13 mu m are found. The washing method of Cu-BTC is examined using three different solvent, (a) ethanol and water of 1: 1 ratio, (b) water, and (c) acetone, to improve the BET surface area. These materials display approximately type I isotherms with no hysteresis and saturation. CO2 adsorption capacities study shows that acetone wash material can store about 5.98 mmol g(-1) of CO2 at 25 degrees C and 1.2 bars.
