Abstract: Supported Ru/HMS zeolite was prepared via the impregnation method.Characterization results showed that HMS was partially covered by ruthenium on its surface, and the degree of irregularity on the catalyst surface was increased.Thus, specific surface area and pore volume of this catalyst were also increased.The Ru/HMS catalyst exhibited efficient catalytic performance towards liquid-phase oxidation of allylic and benzylic alcohols under mild conditions in the presence of molecular oxygen.
