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.

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%.

Key words: Reverse micelles, Nanoparticles, MoO3/ZrO2, Strong solid acid, Isobutane/butene alkylation
