摘要：

TiO2 nanotubes-supported MS (TiO2NTs@MS, M = Cd, Zn) are synthesized by a simple wet chemical method at room temperature. The products are characterized with transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis absorption spectrum and photoluminescence (PL) spectrum. Their optical and morphological properties indicate the interaction between the TiO2 nanotube and MS nanoparticle. The photocatalytic activities of the TiO2NTs@MS are evaluated upon the oxidation of methyl orange under UV light illumination. The results reveal that the photocatalytic efficiency of the nanocomposites strongly depends on the specific interaction between MS and support. (c) 2007 Elsevier Inc. All rights reserved.
