摘　　要：以三嵌段共聚物P123为模板剂,1,3,5-三甲苯为扩孔剂,通过水热反应制备一系列不同孔径的SBA-15。利用N_2脱附-吸附,红外光谱,和X射线衍射对SBA-15的结构进行了表征,结果表明,SBA-15具有有序介孔结构,且孔径在3~6 nm范围内可调。A series of mesoporous SBA-15 with different pore sizes were prepared via hydrothermal method with Pluronic P123 as the template,1,3,5-Trimethylbenzene as pore-enlarging agent. The mesoporous structure of SBA-15 was characterized by nitrogen adsorption-desoption measurements and XRD. The results showed that SBA-15 had typical ordered mesoporous structure and the pore sizes of SBA-15 could be varied from 3 to 6 nm.
