Abstract

Abstract: Ti(IV) 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, N₂ adsorption-desorption isotherms and ²⁹Si 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 St-O-Ti bands, which are marked by the strong absorption at 950~960cm^-1 in IR spectra

Key words: mesoporous materials, Ti（IV）, solution grafting
