| 英文摘要 | we report the preparation and catalytic properties of highly ordered mesoporous fe-ga-sba-15 materials via direct hydrothermal synthesis. gallium and iron ions were introduced directly into the synthesis gel typical for the preparation of sba-15. the resulting materials had hexagonally ordered mesopores of about 6 nm and surface areas >1000 m(2)/g. in fe-sba-15, the iron species were mainly tetrahedrally coordinated in the amorphous silica walls. in the presence of ga (fe-ga-sba-15), fe species were located at the silica surface as isolated species, as determined by raman and diffuse-reflectance uv-vis spectroscopy measurements. the fe species in fe-ga-sba-15 displayed similar properties as the fezsm-5 zeolites toward nitrous oxide decomposition and were active in the oxidation of benzene to phenol by nitrous oxide. ga-sba-15 and fe-sba-15, on the other hand, showed no catalytic activity. compared with fe-al-sba-15, fe-ga-sba-15 displayed greater selectivity to the desired phenol product.
