| 英文摘要 | iron-substituted sba-15 (fe-sba-15) materials have been synthesized via a simple direct hydrothermal method under weak acidic conditions. the powder x-ray diffraction (xrd), nz sorption and transmission electron microscopy (tem) characterizations show that the resultant materials have well-ordered hexagonal meso-structures. the diffused reflectance uv-vis and uv resonance raman spectroscopy characterizations show that most of the iron ions exist as isolated framework species for calcined materials when the fe/si molar ratios are below 0.01 in the gel. the presence of iron species also has significant salt effects that can greatly improve the ordering of the mesoporous structure. different iron species including isolated framework iron species, extraframework iron clusters and iron oxides are formed selectively by adjusting the ph values of the synthesis solutions and fe/si molar ratios.
