摘　　要：文中提供了一种用于CO2吸附与分离的金属有机骨架材料及其制备方法，所述的金属有机骨架材料是由过渡金属离子与多齿有机配体通过共价键或分子间作用力构成的刚性的金属羧基化合物簇状结构，在金属有机骨架材料上修饰有胺类聚合物，所述的用于CO2吸附与分离的金属有机骨架材料的比表面积1048m2／mg孔容0．346cm3／g。该材料可以实现低压条件下气体的选择性吸附，在1大气压下，可以实现2．6％wt的吸附效果。A type of metal -organic frameworks used for CO2 absorption and separation and its preparation method are intro- duced in this paper. The mentioned MOFs is of a rigid metal carbonyl compound cluster structure composed of transition metal ions and muhidentate organic ligand through covalent bond or intermolecular force and is finished with ammonia polymer. Specific surface area and pore volume of MOFs for CO2 absorption and separation are 1 048 m2/mg and 0. 346 cm3/g, respectively. It can realize se- lective absorption of gas under low pressure to achieve absorption effect of 2.6% wt under latm.
