Abstract

Octahedral manganese oxide molecular sieves (OMS-2) was doped with titanium to form hybrid catalyst (Ti-OMS-2) by precipitation method. Atomic absorption and X-ray diffraction analysis indicate the incorporation of titanium into the framework of OMS-2. Infrared and pyridine adsorption measurements demonstrated that Lewis acid sites were created by the presence of titanium in the OMS-2. Ti-OMS-2 is the most active catalyst for the oxidation of cyclohexene with tert-butylhydroperoxide (TBHP) compared to titanium oxide (TiO2) and OMS-2; suggesting a synergetic effect between Ti and OMS-2 in the hybrid catalyst.
