CdxZn1-xS敏化TiO2纳米管阵列电极光电化学制氢

摘要

采用阳极氧化法,在钛片基体上制备出TiO 2纳米管阵列(TiO 2 NTs),利用连续离子层吸附与反应(SILAR)法在TiO 2 NTs上负载 Cdx Zn1-x S固溶体.用场发射扫描电子显微镜(FESEM)、扫描透射电子显微镜(STEM)、X 射线能量散射(EDS)、X 射线衍射(XRD)、紫外-可见漫反射等测试手段对样品进行表征,在自制的三电极反应装置中进行光电制氢测试.结果表明,Cd0．8 Zn0．2 S＠TiO 2 NTs(x＝0．8时)光电制氢活性最好,约为CdS＠TiO 2 NTs活性的4．3倍.%TiO 2 nanotube arrays were firstly prepared on the surface of titanium sheet by the method of anodic oxidation and then Cdx Zn1-x S solid solution were deposited on them through successive ionic layer absorption and reaction technique.The materials were characterized by FESEM,STEM,EDS,XRD and UV-Vis.Hydrogen was generated in the self-made tri-electrode system.The result indicated that Cd0.8 Zn0.2 S@TiO 2 NTs exhibited the best photoelectrochemical activity which was about 4.3 times as much as the activity of CdS@TiO 2 NTs.
