摘    要:改变MOFs材料的中心金属能影响其气体的亲和性和双组份气体的吸附选择性(如比表面积,孔道结构,内部电场等),本文合成并表征了M-DABCO系列(M=Ni, Co, Cu, Zn) MOFs材料。并应用理想吸附溶液理论(Ideal Adsorbed Solution Theory,简称IAST)量化模拟了环境条件下双组分混合气体(组分比CO2:CH4=40%:60%)的吸附选择性。 Ni-DABCO材料具有良好的CO2吸附性能和在环境条件下对CO2/CH4混合气体的吸附选择性。本文通过实验、表征及计算等来讨论中心金属对M-DABCO系列吸附位点的影响。

关 键 词:金属有机骨架  CO2  吸附  混合配体  三乙烯二胺  金属效应

Abstract:Tuning metal center on Metal-Organic Frameworks ( MOFs) had an impact on properties which enhanced affinity of gas adsorption and selectivity in binary gas mixture ( e.g.surface area, cavity, electric field, etc.) .The synthesis and characterization of a X-DABCO series ( X=Ni, Co, Cu, Zn) of MOFs were described.The experiments and the Ideal Adsorbed Solution Theory (IAST )were applied to determine the CO 2/CH4 selectivity.The Ni-DABCO revealed the best performance concerning CO2 adsorption and CH4/CO2 selectivity at ambient conditions. The characterizations, calculations and adsorption experiments were combined to discuss the metal impact on the adsorption site in the M-DABCO series.
Keywords:MOFs  CO2 adsorption  mixed ligand  DABCO  metal effect
