摘　　要：采用氯化锆(ZrCl4)和对苯二甲酸(H2BDC),通过冰乙酸和盐酸改良的溶剂热法合成锆基金属有机骨架材料(Zr-MOFs),可作为理想的二氧化碳(CO_2)捕集与分离材料。研究结果表明:在25℃,吸附压力0.1MPa条件下,Zr-MOFs对CO_2和N_2的吸附量分别为1.47mmol/g和0.089mmol/g,并且在CO_2/N_2体系中对CO_2有较高的分离性能。The zirconium（Zr）-based metal-organic frameworks（Zr-MOFs）,which was hydrothermal synthesized used zirconium chloride（ZrCl4）and 1,4-benzenedicarboxylic acid（H2BDC）,modified by acetic acid and hydrochloric acid solvent,which could be used for carbon dioxide（CO2）capture and separation as a suitable candidate material.The results showed that the adsorption capacity of Zr-MOFs was 1.47 mmol/g and 0.089 mmol/g on CO2 and N2,respectively,under the condition of 25℃ and 0.1 MPa,which had good adsorption property for CO2.
