报道了一种在 FTO 和 TiO2 纳米管 (TNT) 薄膜上制备分散良好的铂纳米粒子 (Pt NP) 的简便方法。通过扫描电子显微镜(SEM)、X射线衍射(XRD)对所制备的Pt/FTO和Pt/TNT薄膜电极进行了表征。结果表明Pt NPs均匀地分散在支撑基体上。电化学研究表明，Pt/TNT 比 Pt/FTO 具有更高的电催化活性和更好的对甲醇氧化中有毒物质的耐受性，这可以归因于 Pt NPs 在 TiO2 纳米管表面的高度分散。本方法对于直接甲醇燃料电池的高性能催化剂的设计具有广阔的前景。
A facile method to prepare well-dispersed Platinum nanoparticles (Pt NPs) on FTO and TiO2 nanotube (TNTs) film was reported. The so-prepared Pt/FTO and Pt/TNT film electrodes are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD). The results show Pt NPs have been dispersed on the supporting matrixs uniformly. Electrochemical investigations indicate that Pt/TNT has higher electrocatalytic activity and better tolerance to poisoning species in methanol oxidation than Pt/FTO, which can be ascribed to the high dispersion of Pt NPs on the TiO2 nanotubes surface. The present method is promising for the design of high performance catalysts for direct methanol fuel cells.
