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 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°C. The influence of the main flue gas components on the CO2 capacity of the material were discussed as well. 相似文献

Zn/Ni/Cu-BTC强化吸附刚果红性能研究 总被引:1,自引:0,他引:1
运用水热合成法制备了一种新型三金属单配体多孔材料Zn/Ni/Cu-BTC,运用氮气吸脱附、扫描电镜、X射线衍射等对材料进行了表征.研究了其常温常压条件下(25℃,1atm)静态吸附刚果红的性能.结果表明,由于三金属不饱和配位点的协同效应导致刚果红在Zn/Ni/Cu-BTC多孔材料上的吸附容量从630mg/g增加到1250mg/g,增加了98.4%.准二级动力学模型和Langmuir吸附模型较好地描述了Zn/Ni/Cu-BTC对刚果红的吸附行为. 相似文献
