Photocatalytic degradation of dye wastewater by CuS/RGO composites
The CuS/RGO composites were prepared using a facile one-step hydrothermal approach.The as-obtained samples were examined by X-ray diffraction(XRD), Raman spectra, scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), Brunner-Emmet-Teller (BET) measurements and UV-Vis spectrophotometry.The results showed that the CuS particles were equably dispersed on the RGO sheets and electronic migration effect existed between RGO and CuS.The photocatalytic performance of CuS/RGO samples was measured by the degradation of Cationic blue SD-BL, Cationic red X-5GN, Direct blue 86, Reactive blue KN-R, Methylene blue and Rhodamine B under irradiation.The photocatalytic experiments showed that the CuS/RGO composites exhibited a better photocatalytic performance for organic dyes with absence of hydrogen peroxide due to the inhibition of recombination of electron-hole pair.Moreover, no significant decline of CuS/RGO photocatalyst for photodegradation of dyes was observed after five cycles, indicating better photostability of the samples.Thus, the CuS/RGO composites could have a promising application in wastewater treatment.
