文摘

Metallic platinum and indium oxide codoped titania nanotubes were fabricated by multicomponent assembly combined with solvothermal treatment. The prepared Pt/In₂O₃-TiO₂ nanotubes exhibited anatase phase with homogeneously dispersed metallic Pt nanoparticles. The material was used as a novel photocatalyst to degrade an aquous phthalate ester under the simulated sunlight irradiation, and the enhanced photocatalytic activity in comparison to In₂O₃-TiO₂ and TiO₂ nanotubes as well as Pt/In₂O₃-TiO₂ nanoparticles was obtained. The enhanced photocatalytic activity is explained in terms of efficient separation of the photogenerated electrons and holes due to the introduction of In₂O₃ and Pt as well as the nanotubular geometries.
