The Ti-doped mesoporous silica MCM-41 materials were synthesized under basic condition at room temperature. The characteristics of samples were investigated by using XRD, HREM, IR, and N-2 adsorption techniques. The results show that Ti ions can get into the Si frame work and lead to the vibration of Si-O-Ti bond, with the increase of Ti ion addition, the mesoporous silica framework structure can be disordered and finally deteriorated
