Increasing amount of CO_2 in the atmosphere caused by human activities has quickly become one of the most urgent environmental issues. CO_2 Capture and Storage (CCS) is a promising option as it can reduce the amount of CO_2 emissions in the atmosphere. It is critical to develop an efficient separation technique for capturing CO_2 from the gas streams. One of the technologies in CCS is utilizing a crystalline porous material called Metal-Organic Frameworks (MOFs). To take the advantages of MOF due to the ease of modification, we designed bio related ligand from natural products in the form of porous framework. Bio-MOFs discussed in this research is made from Chromium (III) Nitrate and Succinic Acid (C_4H_6O_4) as ligand. The synthesis is carried out through hydrothermal reaction method using water as solvent. This research measured Chromium-Succinate MOF’s porous properties, thermal stability, morphology, and chemical functionalities by performing various test such as adsorption/desorption of N_2, thermogravimetric analysis (TGA), scanning electron microscope (SEM), and Fourier Transform Infrared Spectroscopy (FTIR) analysis. The results of this study show that this Bio-MOF based succinic acid (Cr-SA) has surface area of 233 m2/g with pore volume of 0.66 cm3/g. The porosity of Bio-MOF Cr-SA is comparable to other reported Bio-MOFs. Bio-MOF Cr-SA also has good thermal stability which can maintain its structure up to temperatures above 350oC. From the Bio-MOF properties that have been investigated, it is expected that it would be a preliminary study for the use of succinic acid bio-ligands in MOF for CO_2 capture application. |
