采用2-甲基咪唑、4-甲基咪唑和2-乙基-4-甲基咪唑作为添加剂水热法一步合成了金属有机骨架MIL-101，考察了合成条件对样品物相和收率的影响，采用XRD、N2物理吸附、SEM、UV-vis手段对样品进行表征分析，并在动态吸附装置上评价了样品的二氧化碳吸附性能。结果表明，以这3种咪唑衍生物作为添加剂，均可合成具有规则八面体形貌且尺寸均匀的MIL-101样品，合成温度低于180℃，样品最大收率可达70%。4-甲基咪唑辅助合成的MIL-101样品在1.0 MPa压力下对二氧化碳的饱和吸附量可达313mg/g。

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.
