Zeolitic imidazole frameworks (ZIFs) as the special class (subcategory) of metal organic frameworks (MOFs) are constructed by imidazolate linkers and metal ions. These materials have recently attracted intense owing to their permanent porous structure, high thermal stability, tunable pore aperture and large surface area. Consequently, ZIF-67 has the potential to be applied to gas adsorption, drug delivery, catalysis, etc. In this article ZIF-67 was synthesized by solvothermal method, especially for CO2 adsorption. The main objectives of this study were ZIF-67 synthesis in optimum condition including synthesis temprature and molar amount of ligand, and investigated the structure of ZIF-67 using BET analyzer. Optimum synthesis temperature of ZIF-67 was evaluated within room tempreture. Furthuremore, the molar amount of the ligand was. In addition, the CO2 adsorption results showed that the capacity of the optimized ZIF-67 was 51.93 mg/g at 25℃ and atmospheric pressure.
