sonochemical fabrication of pd/tio2-nanotubes/ti plate as a green catalyst for oxidation of alkylarenes and benzyl alcohols

A facile and fast strategy has been employed to fabricate pd nanoparticles supported on tio2 nanotubes/ti plate via sonochemical deposition. microstructure studies showed the homogeneous deposition of pd nanoparticles on the walls of tio2 nanotubes/ti plate. the synthesized plate was applied as a novel catalyst for the oxidation of benzyl alcohol and ethylbenzene derivatives. the results of catalytic experiments demonstrated that the modified plate was an efficient green catalyst for the oxidation of benzyl alcohols to benzoic acid derivatives in h2o. the oxidation of alkylarenes was carried out in etoh:h2o (1:1) ended up with the formation of the corresponding ketone as the sole product. high yields and excellent selectivities were obtained for the oxidation reactions in green solvents using green oxidant. superior catalytic activity, easy catalyst recovery, and reusability of the catalyst are some advantages of the modified pdnps/tio2 nanotubes/ti plate, indicating a potential application of the catalyst in the industrial oxidation reactions.
