▎ 摘　　要

The catalytic activity of TiO2 nanoparticles supported on graphene oxide (GO) namely TiO2/GO is reported in the oxidation of styrene (1) using t-butylhydroperoxide (TBHP) as an oxidant in acetonitrile at 70 degrees C. The oxidation of 1 results mainly in benzaldehyde (2) and styrene oxide (3) using TiO2/GO as catalyst using TBHP as an oxidant. Furthermore, the product selectivity of 3 increases with increasing the wt% of TiO2 on GO under the present reaction conditions. Also, the 5%TiO2/GO catalyst was recycled for four cycles without any drop in conversion of 1 under the present experimental conditions.
