英文摘要	Porous SBA-15 silica with high surface area was used as a support for loading active Pt with low content of 0.5 wt% through a deposition-reduction or impregnation method and further applied for deep oxidation of benzene. These materials were characterized by X-ray diffraction, nitrogen adsorption-desorption, transmission electron microscopy, inductively coupled plasma optical emission spectrometer and X-ray photoelectron spectroscopy techniques. The porous SBA-15 support with high surface area provides a sufficient room for dispersion of Pt nanoparticles. The synthesis routes have a great influence on the chemical-physical properties and catalytic performances of the Pt/SBA-15 catalysts. The catalysts reduced by NaBH4 and H-2 exhibited higher activities than that on air-treated and sodium citrate-reduced samples because of their smaller crystallite size, higher dispersion and negatively charged metallic introduced with a strong metal-support interaction. Complete benzene conversion to CO2 has been achieved at about 145 A degrees C over the best NaBH4-derived Pt/SBA-15 catalyst which was 82 A degrees C lower than that on the catalyst prepared by sodium citrate reduction approach.
