| 中文摘要: |
| 采用溶胶-凝胶法制备的离子液体功能化的二氧化硅对于杂多酸是一种可行的载体，三种商用杂多酸成功的负载在离子液体功能化的二氧化硅上作为醇氧化的催化剂。利用FTIR、XRD、XPS对该种负载离子液相催化剂进行了表征。基于磷钨酸的负载离子液相催化剂活性最好，高产率（大部分> 93 %）的得到了相应的羰基化合物。且该催化剂经过简单的过滤即可回收，重复使用七次效果较好。 |
| 英文摘要: |
| Ionic liquid functionalized SiO2(SiO2-IL) was demonstrated to be an appropriate support for polyoxometalates(POMs), and three kinds of commercially available POMs were immobilized on SiO2-IL as supported ionic liquid catalysis for alcohol oxidation with H2O2. The catalysts were characterized by FTIR, XRD, and XPS. PW/SiO2-IL shows the best activity and high yields (most > 93 %) of corresponding carbonyl products were obtained. In addition, the catalyst can be easily recovered by filtration and reused seven times with good yields. |
