| 摘 要： | 采用水热法合成锐钛矿型TiO2纳米管(TiO2-NTs),并以其为载体制备了Pt/TiO2-NTs复合材料。用TEM、XRD对复合材料的形貌和结构进行了表征,TEM测试表明Pt纳米粒子以簇状形式均匀地分散在TiO2纳米管表面。运用循环伏安法研究了Pt/TiO2-NTs复合材料在不同条件下对硫酸中甲醇的电催化活性,并讨论了甲醇的电氧化机理。结果表明,Pt/TiO2-NTs复合材料具有出色的电催化活性。因此,TiO2-NTs被认为是非常有潜力的燃料电池贵金属催化剂载体材料。

| Abstract: | Anatase TiO2 nanotubes were prepared by a hydrothermal method and Pt/titanium dioxide nanotubes(Pt/TiO2-NTs) composites were successfully prepared through a simple reductive process.The morphology and structure of the resulting composites were characterized by transmission electron microscopy and X-ray diffraction.TEM results show that Pt nanoparticles in nanoclusters morphology are well dispersed on the surface of TiO2-NTs.Electro-oxidation of methanol in sulfuric acid solution was studied by CV in detail ... |
