| 摘 要： | 以表面含氨基的HMS为载体，利用微波法在载体孔内合成8-羟基喹啉铁（FeⅡ-Oxine）、邻苯二酚铁（FeⅡ-Cat）和邻菲洛啉铁（FeⅡ-Phen）负载型催化剂（FeⅡ-L/HMS，L=Oxine，Cat或Phen），再在载体孔口接枝聚酰胺-酯型二代树状分子(A)，制得FeⅡ-L/HMS-A包络合型催化剂。XRD、FT-IR、Fe含量分析和苯酚羟基化反应结果表明，铁配合物能够被有效包络合到HMS孔内，显示出较好的苯酚羟基化活性，具有良好的重复使用性能，是一种介孔分子筛固载金属配合物简便、有效和环境友好的方法。

| Abstract: | Fe^Ⅱ-Oxine, Fe^Ⅱ-Cat and Fe^Ⅱ-Phen complexes inside the pores of the amino-functionalized mesoporous silicas of HMS were synthesized in situ and encapsulated under microwave irradiation. The as-prepared heterogeneous Fen complexes catalysts were characterized by XRD, FT-IR and iron elemental analysis,and their catalytic properties in the hydroxylation of phenol with H202 were investigated. The results indicated that the microwave-assisted method was efficient and environmental-friendly, and could improve the loading of Fe^Ⅱ complexes on HMS. Furthermore, HMS-encapsulated Fe^Ⅱ complexes exhibited better catalytic activity and reusability in catalyzing the hydroxylation of phenol. |
