摘要
Nanocomposites based on cadmium sulfide (CdS) and Na-montmorillonite (Na+-Mt) were prepared by a hydrothermal method using Cd[NH2CSNH2]SO4 complex as precursor of CdS which was derived from cadmium sulfate and thiourea. These nanocomposites were characterized by X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR) and X-fluorescence (XF). The nanocomposites consist of nanosized CdS pillars, which tend to increase in size as the amount of complex precursor increases. The CdS crystals have a hexagonal symmetry. The photocatalytic activity of the obtained CdS-Mt nanocomposites is improved significantly compared to that of the Mt and pure CdS. The resulting CdS-Mt nanocomposites could degrade methylene blue and rhodamine 6G under near UV-visible irradiation. (C) 2013 Elsevier B.V. All rights reserved.
