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.
