对在TiO2纳米管表面上沉积铂进行了研究.HRTEM、XPS结果表明:第一步沉积在粉末TiO2表面上的铂粒为纳米尺寸,系由PtO2和Pt(OH)2组成;第二步制成纳米管后,铂粒在纳米管外表面分布均匀.为下一步以TiO2纳米管作为催化剂载体的研究奠定了基础.
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.
