Abstract

Silver supported hexagonal SBA-15 and lamellar SiO₂-L81 mesoporous silica were prepared via impregnation or co-condensation methods. FTIR, UV-vis., XRD, SEM, and TEM were utilized for determination of their structural properties of the Ag/SiO₂ wasnanocomposites. The analysis confirmed that Ag-NPs were successfully loaded into/onto mesoporous silica (hexagonal SBA-15 and lamellar SiO₂-L81). The loading of Ag-NPs showed a distortion of mesoporous silica structure via impregnation method, whereas it did not alter the mesoporosity structure, when the co-condensation method was used.

银纳米粒子功能化的六角形SBA-15和层状SiO 2 -L81介孔二氧化硅，合成和结构表征

摘要

通过浸渍或共缩合方法制备了载银的六角形SBA-15和层状SiO ₂ -L81介孔二氧化硅。FTIR，UV-vis。，XRD，SEM和TEM用于测定Ag / SiO ₂纳米复合材料的结构性能。分析证实Ag-NPs成功地加载到介孔二氧化硅中（六角形SBA-15和层状SiO ₂ -L81）。Ag-NPs的负载量通过浸渍法显示出介孔二氧化硅结构的变形，而当使用共缩合方法时，它并没有改变介孔结构。
