Stable ordered mesoporous titanosilicates with highly active catalytic sites (MTS-9) have been successfully synthesized from assembly of pre-formed titanosilicate precursors with polymer surfactant (P123) in strongly acidic media. Mesoporous MTS-9 shows good hydrothermal stability in boiling water (over 120 hours). Catalytic data show that MTS-9 is very active catalyst in catalytic conversion of both small molecule of phenol and bulky molecule of 2,3,6-trimethylphenol. The MTS-9 samples were characterized with infrared, UV-Raman, and TEM techniques. The results suggest that the good hydrothermal stability of MTS-9 is attributed to thicker mesoporous wall and zeolite-like connectivity of TO4 (T=Si, Ti) in the mesostructure. The high catalytic activity of MTS-9 are due to the TS-1-like enviroment of the Ti species in MTS-9. © 2003 Elsevier Science B.V. All rights reserved.
