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 (Ni-MOF-74) for CO2
capture and also the recent advances in the development of Graphene Oxide
functionalized Ni-MOF-74 for CO2 capture. In this study, CO2 adsorption on Nickel-
MOF-74 and Nickel-MOF-74-GO 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, Ni-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, Ni-MOF-74 was synthesized by
using nickel (II) nitrate, Ni(NO3)2·6H2O and 2,5-dihydroxyterephthalte acid in the
presence of dimethylformamide (DMF) , ethanol and deionized water under
conventional hydrothermal method. Thereafter, Ni-MOF-74 was grafted with
graphene oxide (GO). MOF provided a high porosity and reactive centers and GO a
dense array of carbon atoms to increase dispersive interactions. The resulting materials
showed a significant enhancement in porosity owing to the formation of pores at the
interface of GO and MOF crystals. GO oxygen groups were identified as nucleation
sites for the formation of the MOF crystals. 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.
