Abstract

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 N₂adsorption 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.

Key words: mesoporous silica MCM-41 materials, Ti-doped, mesopore structure
