Abstract

Abstract: The preparation for depositing Pt on TiO₂ nanotubes was investigated. XPS and HRTEM measurements showed that, firstly, the nanosize Pt particles deposited on powdered TiO₂ consisted of PtO₂ and Pt(OH)₂, then, in the course of TiO₂ nanotube formation the Pt nanopar-ticles were well-distributed on the external surface of TiO2 nanotubes. The results indicate that TiO₂ nanotubes may be a candidate for Pt-catalyst carrier materials.

Key words: TiO₂ nanotube, high-resolution electron microscope （HRTEM）, Pt nanoparticle
