• [16][17][18][19]. However, several studies have indicated that the surface area is not the sole determining factor in CO2 storage at low pressure. For instance, despite having a lower surface area than MOF-177, HKUST-1 exhibited a greater CO2 adsorption capacity of 4.16 mmol·g−1 at 298 K and 1 bar [20

• investigations under 10 bar and 298 K. At pressures higher than 10 bar, computational and experimental results were significantly different because of the unsuitable force field under high pressure conditions. Recently, Stanton et al. also used the GCMC technique to predict the CO2 adsorption of various MOF

• , which promotes their interaction with OMSs within the MOF structures. In this regard, MOFs tend to exhibit instability under such conditions. Therefore, design and selection of MOFs are imperative for effective CO2 adsorption, such as in the case of MOF-808. Furthermore, CO2 storage at low pressure is
