| 摘 要： | 将商业P25 TiO2纳米粒子经传统水热法制备出钛酸纳米管(HTiNTs),再经水热还原法在其表面沉积Pt,经高温煅烧制备出Pt负载锐钛矿型TiO2纳米管(Pt/TiNTs).采用场发射扫描电子显微镜(FESEM)、X射线衍射仪(XRD)及透射电镜(TEM)、能谱(EDS)对其进行表征,并用气相色谱(GC)研究不同Pt担载量的TiO2纳米管对乙酸溶液的光催化分解效果.结果表明:所制备的Pt/TiNTs为锐钛矿型Ti()2,与P25 TiO2相比,Pt/TiNTs对乙酸的光催化分解效果显著提高.

| Abstract: | In this paper hydrogen titanate nanotubes(HTiNTs) are synthesized via a typical hydrothermal method.Pt loaded titanate nanotubes(Pt/TiNTs) are successfully prepared by loading Pt nanoparticles onto the HTiNTs surface with specific hydrothermal reduction conditions,followed by calcination at 773k.The morphology and structure of Pt/TiNTs are investigated by FESEM,XRD,TEM,and EDS.The relationship between the different loading amount of Pt nanoparticles and the photocatalytic activity of Pt/TiNTs is investigate... |
