Synthesis and catalytic performance of titanium-containing mesoporous molecular sieves

Synthetic methods of titanium-containing molecular sieves, such as hydrothermal, ambient temperature, microwave, templating and grafting synthesis, and their characteristics, are discussed. Surface modification techniques for titanium-containing mesoporous molecular sieves are reviewed, and their catalytic performance in catalytic oxidation, alkene epoxidation, hydroxylation,and photocatalysis is also recapitulated.lt is suggested that synthetic methods of titanium-containing mesoporous molecular sieves with high hydrothermal stability, the preparation techniques for those sieves with specific performance by the surface modification, and the research on their catalytic mechanism in photocatalysis and other catalytic fields should be of attraction, and in focus.
