STATIC STUDY OF MODIFIED MOFs WITH AMINES FOR CO2 ADSORPTION

Nowadays, the emission of carbon dioxide (CO2) is the most impact of global warming. Large amount of CO2 is released from consumption of fossil fuels, transportation and many activities. To reduce the amount of CO2 is can be achieved by many physical and chemical methods, for example, absorption, adsorption, CO2 membrane filter and etc.
The development involved with nanotechnology, which selected the Metal Organic Frameworks (MOFs) as nano-material in order to enhance the CO2 adsorption capability. This study is represented by modification of Isoreticular Metal Organic Frameworks (IRMOFs) and modification of IRMOFs with amines. Both of prepared IRMOF-3 and modified IRMOF-3-AMP were synthesized, characterized, investigated and compared for CO2 adsorption capabilities. The IRMOFs is one of the modified MOFs, which is well-known of nano-porous materials. Their high pore volume and specific surface area properties support for CO2 adsorption properties. Besides, the AMP has been selected to attach with IRMOF-3, since the amines-based used to support the CO2 capture capability.
The prepared IRMOF-3 and modified IRMOF-3-AMP was well synthesized and characterized for CO2 adsorption via Brunauer-Emmett-Teller (BET). Moreover, both of the modified MOFs were characterized by using Field Emission Scanning Electron Microscope (FESEM), Fourier Transform Infrared (FTIR), Transmission Electron Microscope (TEM), and Thermogravimetric Analysis (TGA) in order to support the BET analysis as well. The MOFs modifications were expected to achieve great results. However, the prepared IRMOF-3 has shown higher rate of CO2 adsorption as compared with modified IRMOF-3-AMP due to AMP is not so effective after modification with IRMOF-3.The development of CO2 adsorption in this study is important to the industrials regarding environmental concern, since this technology can be used to improve the pollution control and industrial operation hygiene.
