摘要
A novel fabrication route for CdS@TiO2 hybrid coaxial nanocables with the wall thickness controlled precisely is proposed using liquid-phase deposition (LPD) method with porous anodic aluminum oxide (AAO) as templates. Using LPD method, the thickness of the TiO2 sheaths could be controlled precisely by adjusting the reaction conditions. Sequentially, the continuous and polycrystalline CdS nanotubes were deposited onto titanium oxide nanotubes by chemical bath deposition in order to form the coaxial CdS@TiO2 nanocables. The core/sheath nanocables were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and U-V-visible spectroscopic techniques.
