A simple and versatile technique has been developed to prepare TiO2 and TiO2-based composite (TiO2-CdS and TiO2-Au) nanotube arrays. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX) analysis X-ray diffraction (XRD), thermogravimetric analysis (TGA) UV-vis spectroscopy, and photoluminescence (PL) spectroscopy are used to characterize their morphology structure composition and properties. The TiO2 CdS nanotubes contained many TiO2 and CdS quantum dots and exhibited a novel PL band in the blue-wavelength range. The reported strategy will be useful for fabricating nanoparticle-nanoparticle composite nanostructure arrays which are suitable for applications in catalysis, chemical sensors, nanoelectrodes, and nanodevices.
