CdS/Rectorite nanocomposites were prepared through hydrothermal method by using Cd[NH2CSNH2]2Ac2 complex as precursor of CdS which was derived from cadmium acetate and thiourea. The obtained nanocomposites were characterized by X-ray diffraction (XRD), Fourier transfer infrared spectra (FTIR), diffusion reflection spectra (DRS), transmission electron microscopy (TEM) and the selected area electron diffraction (SAED) patterns. Experimental results indicate that CdS exist in at least three forms: CdS adsorbed at surface, CdS pillared in montmorillonite-like layers of Rectorite and CdS pillared in the new layered structure formed during the hydrothermal process. Those CdS crystals are hexagonal symmetry. The photoactivity and photostability of the obtained CdS/Rectorite nanocomposites are improved significantly compared to that of the reference Rectorite and pure CdS.
Graphical abstractCdS/Rectorite nanocomposites were synthesized by hydrothermal method. Its absorptive property and photoactivity for Rhodamine B were enhanced significantly compared with that of the Rectorite. The nanocomposites are expected to be useful in various applications, for instance, adsorption and photodegradation of various organic contaminants.Figure optionsDownload full-size imageDownload as PowerPoint slide
