| 摘 要： | 采用浸渍法制备了H4O40SiW12/SBA-15催化剂,通过红外光谱、X射线衍射、N2吸附-脱附和透射电镜等方法对催化剂进行了表征.结果表明,H4O40SiW12能均匀分散于SBA-15的孔道中,催化剂仍保持载体的介孔结构和硅钨酸的Keggin型结构.将催化剂用于环己酮的Baeyer-Villiger氧化反应中,考察...

| Abstract: | Silicotungstic acid (H4O40SiW12) was supported on SBA-15 with the content of 20% by impregnation. The structure and proper-ties of the catalyst were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, N2 adsorption-desorption, and transmis-sion electron microscopy. H4O40SiW12 was highly dispersed on SBA-15 without structural change. The material was applied as an efficient catalyst for the Baeyer-Villiger oxidation of cyclohexanone under different conditions such as the catalyst amo... |
