摘要：

In this paper, we report the hydrothermal preparation of Cd(OH)(2), nanowires and further conversion to CdO nanobelts, US nanowires and CdSe nanoparticles through thermal treatment, solvothermal and mixed-solvothermal routes, respectively. The as-obtained products were characterized by means of powder X-ray diffraction (XRD), transmission electron microscopy (TEM), and field emission scanning electron microscopy (FEMSEM). Research showed that four cadmium compounds were good photocatalysts for the degradation of organic dyes such as Safranine T and Pyronine B, under irradiation of 365 nm UV light. The order of catalytic activity of different materials was found to be Cd(OH)(2) < CdO < CdS < CdSe. (C) 2009 Elsevier Ltd. All rights reserved.
