Abstract

Octahedral manganese oxide molecular sieve (OMS-2) modified by impregnation of TiO2 exhibits a higher catalytic activity for oxidation of styrene with tert-butylhydroperoxide in comparison to titanium-incorporated OMS-2, where the styrene conversions were ca. 70% and 45-50%, respectively. The framework of titanium species have no effect in the enhancement of catalytic activity, while non-framework of titanium species induces a synergetic effect that enhances the oxidation of styrene with tert-butylhydroperoxide.
