Pd decorated TiO2 nanocrystal with exposed (001) facets was synthesized via solvothermal hydrolysis combining photoreduction deposition route, which exhibited a great enhancement in activity and stability of photocatalytic selective alcohol oxidations under UV light irradiation in aqueous medium. The superior activity of Pd decorated TiO2 nanocrystal with exposed (001) facets was attributed to the synergistic promoting effects of the following factors: firstly, the exposed (001) facets with higher surface energy facilitated the activation of reactant molecules and the photocatalytic oxidation; secondly, the increased oxygen vacancies and enhanced O-2 adsorption on (001) facets could trap photoelectrons and thus, inhibit their recombination with holes; thirdly, the decoration with Pd nanoparticles effectively reduce the photocharge recombination rate by capturing photoelectrons. Meanwhile, this photocatalyst displayed excellent durability owning to the strong Pd-TiO2 interaction against deactivation caused by either Pd leaching or Pd aggregation. (C) 2016 Elsevier B.V.
