| Abstract: | Mesoporous iron oxide silicate nanocomposites Fe2O3-SBA-15 with iron loadings in the range of 1.2wt% -35.8wt% were synthesized by a simple direct hydrothermal method. The as-synthesized samples were characterized by XRD, SEM, UV-vis DRS, TEM and N2 adsorption-desorption. The characterization results showed that mesoporous nanocomposites Fe203-SBA-15 with well-dispersed nanoclusters of iron oxide in the walls of ordered mesoporous silica structures and high surface area were attained under the condition of adjustment of Fe/Si molar ratios and appropriate Fe loadings. |
