摘要：

Ti(TV) was successfully grafted onto the frameworks of MCM-41 material by solution grafting reaction scheme. The product was extensively characterized by XRD, TEM, EDS, FTIR, Na adsorption-desorption isotherms and Si-29 MAS NMR methods. Three mechanisms of the solution grafting reaction were put forward. Experimental results show that the Si-OH groups react with Ti(OBu)(4) and form Si-O-Ti bands, which are marked by the strong absorption at 950 similar to 960cm(-1) in IR spectra.
