| 摘 要： | 利用溶剂热法合成了不同锂含量的MOF-5(x Li-MOF-5,x=0,1,3,5)。在MOF-5结晶过程中,锂离子被合并入其骨架结构中。实验表明,合并入骨架的锂能够改变MOF-5的结构和表面化学性质。不同的x Li-MOF-5能够不同程度降低骨架相互穿插的程度从而导致其吸附分离能力的大幅改变。其中,3Li-MOF-5具有最高的二氧化碳捕获能力(5.47 mmol·g-1),对40%CO2/60%CH4混合气体具有最优吸附选择性。

| Abstract: | Variance lithium content MOF-5 (xLi-MOF-5, x=0, 1, 3, 5) were prepared by using solvothermal method. Lithium cation can be incorporated with MOF-5 during its crystallization process. The experiment demonstrated that lithium incorporation have significantly led different structure and surface chemistry in MOF-5. Different xLi-MOF-5 can reduce framework interpenetration level dissimilarly and lead material with substantially different adsorption separation properties. The 3Li-MOF-5 shows the highest CO2 capacity (5.47 mmol·g-1) and the best selectivity on 40% CO2/60% CH4 mixed gas. |
