Preparation and Characterization of Silica-Based Mesoporous Materials

Abstract:

The silica-based mesoporous materials were synthesized under normal atmospheric with Cetyl trimethyl ammonium bromide(CTAB) as surfactant, TEOS as silica source and hydrochloric acid as activator. The pore sizes distribution of mesoporous materials were adjusted by organic assistant reagent TMB(1,3,5-three toluol).The materials after and before TMB addition were characterized through XRD and IR. The results showed that the materials have regular hexagonal mesoporous structure. The structure is more regular and pore size is more bigger after TMB added.
