Undoubtedly, the formation of all the unique properties of the ZIF nanostructures depends on their proper and perfect synthesis. In this research, a simple and convenient method was used to synthesize ZIF-8 by a eutectic solvent of choline chloride with urea as an ionic liquid without the high energy at room temperature. Also, the effect of different operating parameters affecting the synthesis, such as salt/ligand molar ratio, temperature, ultrasound, and type of ionic liquid, were investigated. To evaluate the performance of this adsorbent, carbon dioxide capture, and equilibrium isotherms of this gas are accomplished at ambient temperature. The results demonstrated that the CO2 uptakes on synthesized ZIF-8 at room temperature in the low and high pressure of 1 and 14 bar are obtained 0.27 and 4.4 mmol/g respectively.
