Abstract:Metal-organic framework,MIL-101 was directly synthesized by the hydrothermal method using 2-methylimidazole,4-methylimidazole or 2-ethyl-4-methylimidazole as additive. The influence of synthesis condition on the products was investigated. The samples were characterized by XRD, N2-adsorption,SEM and UV-vis and were evaluated by CO2-adsorption in a dynamic adsorption device. MIL-101 samples synthesized presented well-defined octahedral morphology and uniform distribution of particles size. Synthesis temperature was lower than 180℃ and the highest yield of MIL-101 sample was 70%. The CO2 adsorption capability of MIL-101 synthesized by 4-methylimidazole was 313 mg/g under 1.0MPa.
