| 摘 要： | 以十二胺为模板在中性条件下合成了Fe-HMS介孔分子筛，研究了不同硅铁比Fe-HMS对苯甲醇催化氧化反应的影响。利用XRD、BET、SEM和H2-TPR等方法对合成的催化剂进行了表征。考察了Fe-HMS对苯甲醇氧化反应的影响。结果表明，Fe3+ 离子进入了分子筛骨架，Fe-HMS分子筛具有均一的蠕虫状介孔结构。焙烧后的Fe-HMS中Fe3+ 主要以Fe2O3形式存在于骨架中。对苯甲醇液相选择性氧化反应，Fe-HMS分子筛的催化活性高于Fe-SiO2。在85℃、Si/Fe摩尔比为25∶1、醇/双氧水摩尔比为1∶2、催化剂含量为4%、反应时间4 h条件下，苯甲醇的转化率和苯甲醛的选择性分别为65.1%和74.6%。

| Abstract: | The iron-incorporated hexagonal mesoporous silica(HMS)material Fe-HMS was synthesized at ambient temperature by using dodecylamine as the template agent,and was characterized by XRD,BET,SEM,H2-TPR and N2 adsorption measurements.Its catalytic performance for oxidation of benzyl alcohol with H2O2 to benzyl aldehyde was investigated.The effects of reaction conditions were examined.The results showed that Fe3+ ions were incorporated into the framework of HMS,and Fe-HMS had a uniform mesoporous structure.Most of... |
