Abstract
Metal organic framework (MOF) is one of extraordinary materials in many technical field applications. One of them is as CO2 gas adsorbent. We studied, synthesized, and characterized Copper-based material, known as Metal organic frameworks (MOFs), using a solvothermal-based modification method. Copper salt (Cu (NO3)2. 3H2O) and benzene dicarboxylic acid (H2BDC) were mixed and then heated in an oven at 120°C, to produce low impurities, small pore and uniform particle size of materials called CuBDC. Infrared spectroscopy and XRD data confirmed the formation of CuBDC. Furthermore, the result showed that CuBDC frameworks have good thermal stability up to 330°C. Thereafter SEM picture showed random, layered, and asymmetrical corners structure which is typical of triclinic crystal system. Lastly, specific surface areas and the porosity were analyzed using The Brunauer-Emmett-Teller (BET) method. It recorded 485 m2.g-1 of surface area while average pore volume and average pore size are 0.16 cm3.g-1 and 5.9 Å respectively. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536869121 1107305727 33554432 0 415 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; mso-ansi-language:IN; mso-fareast-language:IN;}div.WordSection1 {page:WordSection1;}
Highlights
Research on CO2 gas adsorbent materials continue to grow rapidly in line with the increasing volume of CO2 gas formed because of industrial activities
Selectivity to coordinate specific functional group over another would make Metal organic framework (MOF) as potential candidates for the application in molecular sieving or gas separation [13]. It displays that the structure of MOFs can be modified using different solvents which will change the chemical properties and bond strength between adjacent of MOFs layers [14, 15]
Based on the obtained data from X-ray diffraction (XRD), FTIR, and BET, it can be concluded that CuBDC solid is successfully formed with relatively high of crystallinity degree (91 %), and large surface area (485 m2 g-1)
Summary
Research on CO2 gas adsorbent materials continue to grow rapidly in line with the increasing volume of CO2 gas formed because of industrial activities. Increasing concerns about environmental damage and disruption to human health due to the chain effect of these gas in large quantities bring more the need for separation technology or gas purification for specific applications immediately. One of the old technologies for gas separation or purification is using membrane. The separation or purification technology using a membrane is relatively more advantageous because it does not require phase transformation. This is because all the separation methods except the membrane method involve changing the phase from gas to liquid or solid state. The separation technique using the membrane method requires equipment that is relatively simple, compact, easy to control and operate and easy to increase productivity.
