文章以三嵌段共聚物P123为模板剂、正硅酸乙酯为硅源，水热合成了介孔分子筛SBA-15，以3-丙胺基三乙氧基硅烷（APTES）为氨基化剂，采用浸溃法将其嫁接到SBA-15孔内，形成氨基化的SBA-15用于吸附电厂尾气c02。通过氮等温吸附-脱附、XRD、TEM等测试技术对其进行了表征，考察了改性前后SBA-15的吸附性能。结果表明：改性前后的SBA-15对电厂尾气中CO：均具有良好的吸附性能，改性的SBA-15比合成的SBA-15吸附性能要好。

Mesoporous molecular sieves SBA - 15 was synthesized by conventional hydrothermal process using tetraethylorthosilicate（TEOS）as silicon source and triblock copolymer P123 as template. CO2 sorbent were prepared by introducing（3 -Aminopropy） triethoxysilane （APTES） into SBA - 15 using a post - synthetic impregnation method. The synthesized sorbent was characterized by N2 adsorption - desorption, X - ray diffraction （XRD） and transmission electron microscopy （ TEM ）. The adsorption properties of SBA - 15 and modified SBA - 15 were investigated under different and same temperatures. The results indicated that SBA - 15 and modified SBA - 15 both have a good adsorption performance, at the same temperature, the modified SBA - 15 shows better adsorption performance than the synthesis SBA - 15.
