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 microscopy (SEM) and N adsorption analysis. ZIF-8 with the SOD structure and a little 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 CO 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·g while the capacity on ZIF-8 was about 18 mg·g (at 12°C and 0.98 P/ P relative pressure). Furthermore, the impact of flue gas components on adsorption capacity of ZIF-7 and the selectivity of CO against N on ZIF-7 was also investigated in this work. [ABSTRACT FROM AUTHOR] |
