Abstract:
The preparation strategies of Ti-containing silica mesoporous materials, such as direct synthesis and post- synthesis, are reviewed. The features of synthetic techniques and related structure of Ti-containing mesoporous materials are remarked. The important techniques often used to characterize the structure and titanium active sites of Ti-containing mesoporous materials are introduced. The catalytic performances of Ti-containing mesoporous materials used as catalysts for liquid phase selectively catalytic oxidation of organic substrates are summarized. The methods of modification of Ti- containing mesoporous materials aiming at improving the titanium activity, the structure stability, the hydrophobicity and the value of Ti/Si are discussed. The existing problems and suggestions for further research are presented.[著者文摘]
