摘要

A facile method has been developed to incorporate FeOx into the channels of anionic surfactant-templated mesoporous silica (AMS). This synthesized method was based on a novel templating route (S-[MN]I-+(-)), in which Sar-Na (N-Lauroylsarcosine sodium) was employed as structure-directing agent (S-), Fe ion functionalized APATES (N-[3-(Trimethoxysilyl) propyl] ethylenediamine) as co-structure directing agent ([MN](+)). The Fe ion functionalized APATES (Fe[APATES](+)) could establish a critical inter-action between the surfactant head group and silica species by counterion-mediated interaction during the synthesis process. The synthesized samples were characterized with XRD, N-2 adsorption, XPS, FT-IR, UV-vis, H-2-TPR, TEM. The results revealed that FeOx species could be highly dispersed onto the pore channel surface and have a strong interaction with the silica wall. Furthermore, this catalyst of FeOx-AMS exhibited high catalytic performances for the hydroxylation of phenol.
