Table 4: Experimental data of ZIF-8 samples. presence of ZIF-8 lowers the activation energy required for CO2 adsorption by MEA. This would enhance the overall reaction rate, leading to quicker equilibrium attainment. The fact that ZIF-8 increases CO2 loading efficiency implies that further modifications to the ZIF-8 structure (e.g., functionalization with amine groups or optimization of pore size) could potentially lead to even greater enhancements in CO2 capture efficiency when combined with MEA. The contribution of ZIF-8 to CO2 loading could also be linked to its microstructure, where the interconnected pore networks allow for more effective diffusion and capture of CO2 molecules, particularly in a dynamic system like the MEA solution. This could explain why the largest particle size (ZS3) shows the highest performance--it likely offers the most accessible pore structure. The CO2 adsorption mechanism in ZIF-8 involves surface adsorption, pore diffusion, and chemical interaction. Initially, CO2 molecules approach the surface of ZIF-8, attracted by its porous structure.
