采用水热法合成了一种新的含铝多孔金属有机骨架材料(Metal-organic frameworks,MOFs)Al12 O(OH)18 (H2O)3 (Al2 (OH)4) [btc]6·24H2O (MIL-96(Al),并用高压吸附仪测试了MIL-96在不同压力和温度下对CO2和SO2的吸附性能.结果表明,该配合物BET和Langmuir比表面积分别为507m2/g和668m2/g,热稳定性较好,温度低于350℃时结构较稳定.在相同温度和压力条件下,MIL-96对CO2的吸附性能远远高于对SO2的吸附性能；在较低温度下,温度越高,MIL-96吸附能力越强,但在100℃时的饱和吸附量(4.27mmol/g)小于80℃时的饱和吸附量(5.15mmol/g),这种现象是由于水蒸气的逸出造成的.
