摘要
利用高稳定性的UiO-66系列金属有机骨架多孔材料制备金属有机气凝胶材料,制得的UiO-66系列金属有机气凝胶材料具有多级孔结构和较高的比表面积,在气体吸附分离领域具有较大应用潜力.气体吸附实验结果表明,UiO-66-NH2金属有机气凝胶材料具有极佳的CO2吸附性能和CO2/CH4分离性能,通过理想吸附溶液理论计算得出其吸附选择性高达18.3.
A series of UiO-66 metal-organic frameworks(MOFs) with excellent stability was used to prepare metal-organic aerogels as a feasible way for the modeling of MOFs. The as-prepared UiO-66-based metal- organic aerogels(MOAs) possessed hierarchical pore structure and high surface area, which were very promising in gas adsorption and separation applications. In gas adsorption measurements, the amine modified UiO-66-NH2 aerogel exhibited outstanding adsorption capacity towards CO2 and high selectivity up to 18.3 towards CO2/CH4 mixture(molar ratio, 1 ∶ 1) calculated through ideal adsorbed solution theory.
