摘要:
以硝酸镍为金属离子源、对苯二甲酸为配体，N， N-二甲基甲酰胺为溶剂，采用溶剂热法合成了金属-有机骨架Ni-MOF，采用X射线粉末衍射、N2吸附/脱附、扫描电镜、红外光谱和热重分析等方法对样品进行表征，考察了反应时间对样品结构及吸附性能的影响，测试了样品的CO2的吸附性能。结果表明， 150 ℃反应4 h后得到Ni-MOF球形晶体，延长反应时间对Ni-MOF的结构及性能没有明显影响。样品的BET面积为1 200～1 221 m2/g，平均孔径为1.95 nm，在常压27 ℃时，对CO2的吸附量为17.9%，经10次吸附/脱附循环实验后，吸附量稳定在16.5%～17.9%，是一个良好的吸附材料。
Abstract:
Ni-MOF was successfully synthesized by the solvethermal method, with nickel nitrate as the metal ion source, terephthalic acid as the ligand and n-dimethyl formamide as the solvent. Such methods as powder X-ray diffraction (PXRD), N2 absorption/desorption, scanning electron microscope (SEM), infrared spectroscope (IR) and thermogravimetric analysis (TGA) were adopted to characterize synthesized Ni-MOF, investigate the effects of reaction time on its crystal structure and test its CO2 absorption property. Experimental results show that tiny crystals of Ni-MOF with spherical morphology were produced after reaction at 150℃ for four hours; prolonging the reaction time had no significant effects on the structure and properties of Ni-MOF. The sample has a BET surface area of 1 212 m2/g and an average aperture of 1.95 nm. CO2 adsorption studies show that this material could absorb 17.9% of CO2 at 27 ℃ and atmospheric pressure. The CO2 adsorption capacity stabilized at 16.5%～17.9% after ten cycles of absorption/desorption experiments, which prove that it is a very good absorbent.
