Preparation and Characterization for Depositing Platinum on TiO2 Nanotubes
载铂TiO2纳米管的制备与表征

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.
