| 摘 要： | 采用水热合成法，通过改变配体中2-氨基对苯二甲酸的含量制备了不同氨基含量的NH2-MIL-53（Al），考察了氨基含量，氨基功能化方法和氨基种类对NH2-MIL-53（Al）的CO2吸附性能的影响。傅里叶变换红外光谱表征（IR）发现在3500～3900 cm-1处存在-NH2基的伸缩振动带，氨基修饰成功。低压下，NH2-MIL-53（Al）的CO2吸附容量随氨基含量的增加而增大，且当氨基含量100%时，其CO2吸附性能优于直接合成的NH2-MIL-53（Al）。合成前修饰比合成后修饰，更有利于提高CO2吸附容量。采用乙醇胺、1，8-二氮杂二环5.4.0]十一碳-7-烯、N，N'-二亚乙基三胺进行后氨基功能化都不能提高MIL-53的CO2吸附能力。

| Abstract: | With the hydrothermal synthesis method, MIL-53(Al) of different amino contents was prepared by changing the content of 2-amino terephthalic acid in ligands. The CO2 adsorption of NH2-MIL-53(Al) was investigated by varing the content, type of amino group and amino functional methods to improve the CO2 capture performance of MIL-53(Al). The synthesized materials were characterized with XRD, TG, infrared spectroscopy and N2 adsorption measurements, and the adsorption performance of NH2-MIL-53 towards CO2 was also investigated on the basis of the adsorption isotherms. The IR results indicated that the peak of —NH2 was found in the range of 3500—3900 cm-1, demonstrating that amino group was loaded successfully. The performance of CO2 adsorption kept fitting with the amino group content of NH2-MIL-53(Al), and when amino group content was 100%, better CO2 adsorption than MIL-53(Al) prepared directly was observed. In addition, when MEA, DBU and MMEN were used for post-synthesis modifications, they all could not improve the adsorption performance of NH2-MIL-53(Al) towards CO2. |
