    摘要:

    通過離子交換和沉淀反應制備納米復合材料CdS/TiO2NTs。采用X射線衍射(XRD)、掃描電鏡(SEM)、透射電鏡(TEM)、漫反射紫外-可見吸收光譜(DRUVAS)、熒光光譜(FES)、X射線熒光分析(XRF)等手段對該復合材料的結構進行表征。SEM結果表明：鈦酸鹽納米管的形成經由TiO2顆粒-片狀的鈦酸鹽-卷曲的鈦酸鹽納米管的自組裝過程。XRD、DRUVAS、FES和FES結果表明：平均粒度大約 8 nm 的六方相CdS均勻的負載于銳鈦礦型TiO2納米管表面，其吸收邊擴展到可見區(qū)。與TiO2納米管及TiO2粉末相比，CdS/TiO2NTs 納米復合材料展示了較高的可見光催化分解水產氫活性

    Abstract:

    The CdS/TiO2NTs nanocomposite was prepared through ion-exchange and precipitation reactions. The nanostructure properties of the composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), diffuse reflectance UV-visible absorption spectra (DRUVAS), fluorescence emission spectra (FES) and X-ray fluorescence analyzer (XRF). SEM results revealed that the lamellar sodium trititanate originating from the TiO2 particles individually curled to form the sodium trititanate nanotubes by self-assembled mechanism. The results of XRD, TEM and DRUVAS demonstrated that hexagonal phase CdS with about 8 nm particle size were homogeneously loaded on the surface of anatase TiO2NTs and the absorption edge of the composite was extended to the visible region. The CdS/TiO2NTs composite exhibited the highest activity of hydrogen production (1708 mL/g) by photocatalytic water decomposition in comparison with TiO2NTs and TiO2 powder under visible light irradiation (l > 400 nm) for 6 h
