利用聚醚P123对双金属材料Fe-Zr进行改性合成介孔材料Fe-Zr（P）,再利用四乙烯五胺（TETA）对Fe-Zr（P）进行功能化制得TEPA（n）/Fe-Zr（P）。采用X射线衍射、X射线光电子能谱、红外光谱、N2吸附-脱附、热重分析等技术对材料结构和热稳定性进行表征,并对CO2吸附性能进行测试。结果表明:P123存在于载体孔道内部;利用TETA对Fe-Zr（P）进行功能化,通过N与Zr配位,从而固载于Fe-Zr（P）表面;温度低于182℃时,TEPA（n）/Fe-Zr（P）保持稳定;TEPA（n）/Fe-Zr（P）中羟基和氨基同时与CO2反应,产生化学吸附,从而提高化学吸附量和N利用率;TEPA质量分数为30%,温度为75℃,气体流速为10 mL/min时,TEPA（30）...

A mesoporous material of Fe-Zr(P) was synthesized by modifying the bimetallic material of Fe-Zr with polyether P123. Then, TEPA(n)/Fe-Zr(P) was prepared by modifying Fe-Zr(P) with tetraethylenepentamine (TEPA). X-ray diffraction, infrared spectroscopy, X-ray photoelectron spectroscopy, N2 adsorption-desorption and thermogravimetric analysis were used to analyze the structure and thermal stability of the synthesized materials. The results show that P123 is remained in the pore channels of the support. Besides, TEPA was introduced to the surface ...
