Abstract: Bimetallic (Sn/Ti) modified mesoporous material with thermally stable and highly active Ti-sites (Sn/Ti-MS-1) was synthesized by the assembly of Sn-incorporated TS-1 precursor with surfactant in acidic media. The characterization results indicated that the material has typical mesostructure and that the mesoporous framework contains zeolitic building units. In the oxidation of phenol and 2,3,6-trimethylphenol with aqueous H2O2, as-synthesized and calcined Sn/Ti-MS-1 both showed good catalytic conversions, indicating that the active Ti-sites are highly thermally stable and that the material is favorable in the oxidation of bulky substrates. Also, Sn/Ti-MS-1 displayed high reaction rate in the oxidation of 2,3,6-trimethylphenol.

Key words: Bimetallic modified mesoporous, Thermally stable sites, Zeolite precursor, Bulky substrate
