摘　　要：一种新型三维多孔金属有机框架材料Zn(BTC)_(4)(均三苯甲酸:BTC=benzene-1,3,5-tricarboxylic acid)通过水热方法合成,并采用二次生长法合成了一种新型金属有机框架/多孔氧化铝复合膜。利用扫描电子显微镜对形貌进行了表征,通过热重量分析探究了复合膜的稳定性,最后测试了该复合膜对CO_(2)/CH_(4)的选择性吸附性能。结果表明,金属有机框架/多孔氧化铝复合膜对CO_(2)/CH_(4)的选择性吸附性能比多孔阳极氧化铝膜高约38%。A novel three-dimensional porous Zn(BTC)_(4)(BTC=benzene-1,3,5-tricarboxylic acid)was synthesized by solvothermal method,and a novel MOF/porous anodic alumina composite membrane was synthesized by secondary growth method.The morphology was characterized by scanning electron microscopy(SEM),and the thermal stability of the composite membrane was investigated by thermal gravimetric analysis(TG).Finally The CO_(2)/CH_(4) selective adsorption performance of the MOF/porous anodic alumina composite membrane was tested.The results shows that the selective adsorption performance of MOF Zn(BTC)4/porous anodic alumina composite membrane for CO_(2)/CH_(4) is about 38%higher than that of porous anodic alumina membrane.
