Synthesis,characterization and experimental investigation of Cu-BTC as CO2 adsorbent from flue gas

Porous Cu-BTC material was synthesized by the solvothermal method.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 CO 2 adsorption capacity but also good selectivity of CO 2 over N 2 by means of packed bed tests.The adsorption capacity of Cu-BTC for CO 2 was about 69 mL/g at 22°C.The influence of the main flue gas components on the CO 2 capacity of the material were discussed as well.
