XRD and IR show that titanium is effectively embedded into framework of HMS, and the order degree of mesoporous HMS doesn't fall down.Embedding content of Ti corresponds well with n(Ti)/n(Si), and the most one is up to 1.61 mmol Ti per g HMS. The intensity of 960 cm -1 band on the IR spectra of Ti-HMS samples takes direct proportion to embedding Ti content. It is shown that this peak may be caused with distortion of SiO 4 tetrahedron that titanium atom incorporate into the mesoporous framework. In catalyzing the epoxidation of styrene, Ti-HMS catalyst can effectively catalyze the oxidation of styrene by TBHP into styrene oxides (65%～86%), phenylacetaldehyde (6%～15%) and benzaldehyde (8%～20%). Be used repeatedly without to be loss of activity. The preparation and reaction conditions of Ti-HMS have the different influences on its catalytic activity and product selectivity.
