主 题：ZIF-7 structural stability CO2 capture ther- mal stability
摘 要：Porous ZIF-7 with the sodalite （SOD） cage structure （ZIF, Zeolitic imidazolate framework） were synthesized by the solvothermal method. Synthesized material was characterized by powder X-ray diffraction （PXRD）, thermal gravity （TG）, scanning electron micro- scopy （SEM） and Na adsorption analysis. ZIF-8 with the SOD structure and a littl larger pore window was synthesized in a similar way and was characterized for comparisons. Thermal stability and structural stability of ZIF-7 were tested through PXRD analysis, and the capability of the material for CO2 capture from simulated flue gas was investigated through physical adsorption method. The results showed that CO： adsorption capacity on ZIF-7 was about 48 mL. gl while the capacity on ZIF-8 was about 18mg.g-1 （at 12C and 0.98 P/Po relative pressure）. Furthermore, the impact of flue gas components on adsorption capacity of ZIF-7 and the selectivity of CO2 against N2 on ZIF-7 was also investigated in this work
