Powder X-ray diffraction （PXRD） was used to test the phase purity of the synthesized material and investigate its structural stability under the influence of flue gas components. The thermal stability of the material was determined through thermal gravimetric （TG） analysis. Scanning electron microscopy （SEM） was employed to study the microstructure of the material. Cu-BTC was demonstrated not only to have high CO2 adsorption capacity but also good selectivity of CO2 over N2 by means of packed bed tests. The adsorption capacity of Cu-BTC for CO2 was about 69 mL/g at 22℃. The influence of the main flue gas components on the CO2 capacity of the material were discussed as well.展开更多
