چکیده انگلیسی
Mesostructured titanosilicates (JQW-3 and JQW-4) have been successfully hydrothermally synthesized from assembly of titanosilicate precursors with quaternary alkylammonium surfactants under alkaline and acidic conditions. Mesoporous JQW-3 and JQW-4 show highly hydrothermal stability in boiling water (over 100Â h) as compared with that of conventional Ti-MCM-41. The catalytic results show that JQW-3 and JQW-4 are very active in a series oxidations and the catalytic activity is similar to that of TS-1, and higher than that of Ti-MCM-41.
