摘　　要：采用三嵌段共聚物F127/CTAB为共模板剂,正硅酸乙酯(Tetraethyl orthosilicate)为硅源,以水热法制备模板剂不同配比下的多级介孔硅。利用红外光谱仪(FT-IR)、紫外分光光度计(UV)、氮吸附脱附(N 2 adsorption desorption)、热重分析(TG)、差示扫描量热仪(DSC)、扫描电镜(SEM)对介孔硅结构进行了表征,并就其对农药三唑酮的吸附行为进行了研究。结果表明:FC-MCM-48较MCM-48有更多的微孔结构。其中FC-MCM-48-1出现了较宽的孔径分布,但多级孔道不明显;FC-MCM-48-2和FC-MCM-48-3出现了间层-介孔的结构。与其他样品相比FC-MCM-48-3对三唑酮的负载量保有较高的水平,而其间层-介孔结构有利于三唑酮的分级释放。Different composition of Hierarchical Porous Materials was prepared through hydrothermal method using F127/CTAB as co-templates,methyl silicate(TEOS)as silicon source.And the mesoporous silica was characterized by FT-IR、UV、N 2 adsorption desorption、TG、DSC、SEM and TEM.Moreover,its adsorption behavior of pesticide triazolone was studied.The results show that FC-MCM-48 has more microporous structure than MCM-48,The sample FC-MCM48-1 has a wide pore diameter distribution,but not obvious.FC-MCM-48-2 and FC-MCM--48-3 have interlayer-mesoporous structure,Compare with other samples FC-MCM-48-3 has a relatively high load of triadimefon,and its interlayer-mesoporous structure is conducive to the graded release of triadimefon.
