Effect of Ti-Doping on the namework Structure of Mesoporous Silica

Chunhu Li

Abstract

The Ti-doped mesoporous silica MCM-41 materials were synthesized under basic conditionat room temperature. The characteristics of samples were investigsted by using XRD, HREM, IR,and N2 adsorption techniques. The results show that Ti ions can get into the St frame work andlead to the vibration of St-O-Ti bond, with the increase of Ti ion addition, the mesoporous silicaframework structure can be disordered and finally deteriorated.
