摘要
利用溶剂热法合成了一种新型的六羧基铜(Ⅱ)配合物(Cu-MOF)。采用粉末XRD、元素分析、热重分析、红外光谱、SEM和低温N2吸附等测试方法对样品的结构和性能进行了表征,并测试了其77K的储氢性能。结果表明,六羧基铜(Ⅱ)配合物具有丰富的微孔结构,BET和Langmuir比表面分别为2166.3m2·g-1和3484m2·g-1,总孔容积Vp(N2,0.997)为1.24cm3·g-1。77K、4.2MPa时的过量氢气吸附量为4.67%,77K、7.4MPa时总氢气吸附量为7.23%。
Cu (]I)hexacarboxylate framework (Cu-MOF)material was synthesized by solvothermal reaction. The properties of the resulting products have been characterized by using XRD, elemental analysis, TG, IR, SEM and low temperature nitrogen adsorption-desorption techniques. The results showed that the product had rich microporous structure, the BET and Langmuir specific surface area were 2166.3m2·g^-1 and 3484m2·g^-1 respectively,and the total pore volume Vp (N2 ,0. 997)was 1.24cm3·g^-1. The material showed an excess H2 uptake of 4.67wt% at 4. 2MPa and 77K,and a total H2 uptake of 7.23wt% at 7. 4MPa and 77K.
