摘要：
A novel method for preparing Ti-MCM-41 has been developed. A series of Ti-MCM-41 have been synthesized with different inorganic titanium salts as Ti sources and characterized by XRD, N-2 adsorption, FT-IR and UV-Vis spectroscopy. The hydrolysis rate of inorganic titanium salts was decreased by adding coordination agent to avoid the formation of TiO2. The characterization results show that most Ti4+ are isolated and tetrahedrally incorporated into the framework of MCM-41. The nature of inorganic titanium salts has a considerable influence upon the incorporation of Ti into the silica framework. (C) 2002 Published by Elsevier Science B.V.
