Abstract

Currently, CO2 capture is a topical issue in environmental preservation and sustainable growth in development. This review highlights the recent studies on synthesis and characterization in metal organic framework (Mg-MOF-74) for CO2 capture and also the recent advances in the development of amine functionalized Mg-MOF-74 for CO2 capture. In this study, CO2 adsorption on Magnesium-MOF-74 and Magnesium-MOF-74-AMP were investigated and compared. Fitting in as fascinating class of nano-porous materials, MOFs have been considered potential candidates for CO2 capture due to its capability of adsorption. However, water stability is often considered a big weakness of all kinds of metal-organic framework structures available for now. As such, Mg-MOF-74 does not exhibit such degradation which has a characteristic of strong coordination bond strength and remarkable as one of the highest CO2 uptake capacity among MOFs. Here, Mg-MOF-74 was synthesized by using magnesium nitrate, Mg(NO3)2·6H2O and 2,5-dihydroxyterephthalte acid in the presence of dimethylformamide (DMF) , ethanol and deionized water under conventional hydrothermal method. Thereafter, Mg-MOF-74 was grafted with 2-amino-2-methyl-1-propanol (AMP). Characterization techniques applied are Fourier transform infrared (FTIR), thermogravimetry analysis (TGA), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), and the performance of CO2 adsorption on both MOFs is studied using BET method. It was found that amine grafted MOF-74 (MOF-74-AMP) has higher CO2 adsorption capacity with a reported value of 0.0046mol/g as compared to MOF-74 with a reported value of 0.002mol/g. This work may be helpful in the integration of amine-grafted MOF-74 applications in CO2 capture.
