| 摘 要： | 利用AOT/异辛烷反胶束体系制备了MoO3/ZrO2纳米粒子.TEM结果表明,反胶束法制得粒子的粒径均匀,95%以上处于38～60nm之间.将此纳米粒子负载于γ-Al2O3上,呈现高度分散状态.NH3-TPD和烷基化反应的测定结果表明,其酸量和反应活性明显高于浸渍法和溶胶-凝胶法制备的样品,烷基化产物中C8的含量在79%左右. |
| 关 键 词： | 反胶束 纳米粒子 MoO3/ZrO2 固体强酸 异丁烷-丁烯烷基化 |

| Abstract: | MoO3/ZrO2 nanoparticles were synthesized in AOT/isooctane reverse micelle system. The transmission electron microscope(TEM) results indicate that the size distribution of nanoparticles is normal and the size of more than 95% particles is between 38 and 60 nm. MoO3/ZrO2 particles was loaded on γ -Al2O3 and present a high dispersity. According to NH3-TPD and alkylation,MoO3/ZrO2 particles apparently have more acid sites and higher activity than those prepared by using impregnation and sol-gel method. The yield of C8 is about 79%. |
| Keywords: | Reverse micelles Nanoparticles MoO3/ZrO2 Strong solid acid Isobutane/butene alkylation |
