摘　　要：The surface-grafted titanium MCM-41 materials were prepared by anchoring titanocene onto the inner walls of MCM-41. The materials were characterized by powder X-ray diffraction （XRD）, N2 adsorption--desorption isotherm and diffuse reflectance UV-visible （UV-vis） spectroscopies. The catalytic properties of Ti-MCM-41 were tested in oxidation of 4-tert-butyltoluene with tert-butylhydroperoxide （TBHP） in liquid phase. MCM-41 with loading 4.8 tool% Ti gave the maximal conversions of 23.6% of 4-tert-butyltoluene with a complete selectivity to 4-tert-butylbenzaldehyde.The surface-grafted titanium MCM-41 materials were prepared by anchoring titanocene onto the inner walls of MCM-41.
