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

Abstract:

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 μm were found. The washing method of Cu-BTC was examined using three different solvent, (a) ethanol and water (1:1), (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 mmolg^-1of CO₂ at 25^oC and 1.2 bar.
